郁金香是这里的主角 Tulips run the show

库肯霍夫花园, 利塞, 荷兰

想象一下，一朵花引发了一场金融狂潮。听起来不太可能，对吧？然而，在17世纪30年代，郁金香在荷兰却做到了这一点。在郁金香狂热时期，稀有的郁金香球茎成了奢侈品，交易价格惊人——有些球茎的价值甚至堪比一栋房子。为什么如此珍贵？因为颜色和条纹图案独特的郁金香稀少且难以预测，收藏家们想要找到他们所能找到的最稀有的品种。

郁金香泡沫最终破灭，但荷兰人对郁金香的热爱却从未消退。几个世纪后，这种与郁金香的深厚情缘又迎来了新的篇章：位于利瑟附近的库肯霍夫花园，也就是今天照片中的这片花园。这座花园于1950年开放，最初是一个春季展览会，荷兰球茎种植者在此向买家和游客展示他们最新的品种。

每年秋季，约有40位园丁会种植超过700万株球茎植物，层层叠叠，营造出色彩缤纷的景象，一直延续到来年春天。其中，约800种郁金香是主角，而葡萄风信子和水仙花则点缀着蓝色和黄色，带来一抹亮丽的色彩。美中不足的是，这座花园每年只对公众开放几周。

Keukenhof Gardens, Lisse, Netherlands

Imagine a flower sparking a financial frenzy. Sounds unlikely, right? Yet in the 1630s, tulips did exactly that in the Netherlands. During tulip mania, rare bulbs became luxury items traded for astonishing sums—some valued at prices comparable to a house. Why so valuable? Unusual colors and striped patterns were scarce and unpredictable, and collectors wanted the rarest varieties they could find.

The bubble eventually burst, but the country's fascination with tulips never faded. Centuries later, that long relationship with the flower found a new stage: Keukenhof Gardens near Lisse, seen in today's image. Opened in 1950, the park began as a spring exhibition where Dutch bulb growers presented their newest varieties to buyers and visitors.

Each autumn, about 40 gardeners plant over seven million bulbs in layered designs so colors appear in waves through spring. Around 800 varieties of tulips lead the show, while grape hyacinths and daffodils add bursts of blue and yellow. The catch? The garden opens to the public for only a few weeks each year.

历史镌刻于石上 History anchored in stone

贝伦塔, 里斯本, 葡萄牙

昔日，离开里斯本的船只在驶向浩瀚的大西洋之前，都会经过一座小小的石塔。这座矗立在塔霍河畔的石塔，既是守护者，也是告别的象征。让我们一起来认识贝伦塔——这座见证葡萄牙扬帆起航，迈入大航海时代的堡垒。

这座塔楼建于16世纪初葡萄牙国王曼努埃尔一世统治时期，在探险家们探索新航线时，它曾帮助保卫里斯本港。其曼努埃尔式设计融合了哥特式风格和航海符号——石绳、盾牌以及海洋主题的雕刻，都清晰地体现了其与海洋相关的用途。

这座塔楼曾矗立在一个小岛上，但随着河岸的移动，它逐渐靠近了陆地。塔楼内曾设有大炮、士兵，甚至还有囚犯。如今，这座联合国教科文组织世界遗产证明，有些地标建筑的确经受住了时间的考验，屹立不倒。

Belém Tower, Lisbon, Portugal

Ships leaving Lisbon once passed a small stone tower before meeting the wide Atlantic. That tower, standing on the bank of the Tagus River, served as both a guardian and a farewell. Say hello to Belém Tower—a fortress that watched Portugal sail into the Age of Exploration.

Built in the early 1500s under King Manuel I of Portugal, the tower helped defend Lisbon's harbor while explorers set out to chart new sea routes. Its Manueline design mixes Gothic forms with maritime symbols—stone ropes, shields, and sea-inspired carvings that clearly embraced their oceanic purpose.

The tower once stood on a small island, but shifting riverbanks brought it closer to land. Inside were cannons, soldiers, and even prisoners. Today, this UNESCO World Heritage Site is proof that some landmarks truly stand the test of time and tide.

有格调的玻璃 Glass with class

维托里奥·埃马努埃莱二世拱廊的玻璃穹顶

由建筑师朱塞佩·门戈尼设计，于1877年竣工的维托里奥·埃马努埃莱二世拱廊位于意大利米兰，是世界上最古老、最著名的购物拱廊之一。它坐落于米兰大教堂广场和斯卡拉广场之间，拥有令人惊艳的玻璃铁艺屋顶和优雅的八角形布局。这条拱廊被亲切地称为“米兰的客厅”，汇集了众多高端精品店、历史悠久的咖啡馆以及知名餐厅。

多年来，米兰拱廊经历了多次修缮，包括20世纪50年代为修复二战造成的破坏而进行的大规模修缮，80年代为保护原有结构而进行的修缮，以及最近为迎接2015年世博会而进行的修缮。拱廊最标志性的特色之一是镶嵌在地板上的公牛马赛克，游客们会绕着它旋转以求好运。拱廊内还有四幅分别代表欧洲、亚洲、非洲和美洲的马赛克镶嵌画，引人注目。它至今仍是米兰优雅与文化底蕴的象征，吸引着当地居民和游客。

The glass dome of Galleria Vittorio Emanuele II, Milan, Italy

Designed by architect Giuseppe Mengoni and completed in 1877, the Galleria Vittorio Emanuele II in Milan, Italy, is one of the world's oldest and most famous shopping arcades. Located between Piazza del Duomo and Piazza della Scala, it features a stunning glass-and-iron roof and an elegant, octagonal layout. Affectionately known as 'Milan's living room,' the Galleria is home to high-end boutiques, historic cafés such as Caffè Biffi and Camparino in Galleria, and renowned restaurants.

Over the years, the Galleria has undergone several restorations, including major projects in the 1950s to repair damage caused by World War II, in the 1980s to preserve the original structure, and most recently in preparation for the 2015 Expo. One of the most iconic features is the bull mosaic set into the floor, around which visitors spin for good luck. Among its notable features are four mosaics representing Europe, Asia, Africa, and America. It remains a symbol of Milan's elegance and cultural sophistication, attracting locals and tourists.

向树木致敬 A tribute to trees

大沼泽地松林

植树节旨在颂扬树木的无声力量——它们如何稳定生态系统、庇护野生动物、为城市降温，并塑造我们日常生活所依赖的环境。在美国，植树节定于四月的最后一个星期五，这一天鼓励美国以及许多其他国家（日期因生长季节而异）的社区种植、保护和养护各种类型的森林，从社区绿荫到标志性的荒野。

在佛罗里达州的大沼泽地国家公园（联合国教科文组织世界遗产地），高地松林耸立于沼泽和草原之上，共同构成了世界上最大的湿地系统之一。图中可见，阳光普照的火炬松和锯棕榈营造出开阔的林地，与大沼泽地广袤的湿地和红树林形成鲜明对比。在植树节这一天，这样的景观清晰地提醒着我们，树木对于这片非凡的亚热带生态系统的健康和平衡是多么重要。

Arbor Day

Arbor Day celebrates the quiet power of trees—the way they steady ecosystems, shelter wildlife, cool cities, and shape the environments we rely on every day. Observed in the United States on the last Friday in April, the day encourages communities here—and in many other countries, where dates vary according to growing season—to plant, protect, and care for forests of every kind, from neighborhood canopies to iconic wildlands.

In Florida's Everglades National Park, a UNESCO World Heritage Site, elevated pinelands rise above the marshes and prairies that form one of the world's largest wetland systems. Seen here, sunlit slash pines and saw palmetto create open woodlands that contrast sharply with the Everglades' vast wetlands and mangrove forests. On Arbor Day, landscapes like this offer a clear reminder of how essential trees are to the health and balance of this remarkable subtropical ecosystem.

莎士比亚日

每年4月23日，世界都会再次聚焦威廉·莎士比亚的生平与遗产。这位剧作家的文字，至今仍在全球文学舞台上熠熠生辉。“莎士比亚日”既是他于1616年逝世的纪念日，也被普遍视为他1564年的诞辰。这一巧合般的日期，为这位重塑英语文学的伟大作家赋予了象征性的意义。从《哈姆雷特》中对人性深处的探寻，到《罗密欧与朱丽叶》里跨越生死的爱情，他的语言至今仍回荡在课堂、剧院与日常表达之中。莎士比亚的作品已被翻译成多种语言，并在世界各地不断上演，跨越时间与文化，持续影响着一代又一代人。

今天的图片展示的是位于英国斯特拉特福德镇的安妮·海瑟薇小屋，这里是威廉·莎士比亚未来妻子的童年故居。这座建于15世纪的茅草屋如今被保存为博物馆，为人们提供了一个难得的窗口，得以一窥这位年轻剧作家成长年代所处的日常生活环境。游客可以在这里探访保留下来的原始结构、历经数百年的家具陈设，以及以都铎时代生活为灵感打造的花园。在这样充满历史气息的空间中，人们也更容易沉浸其中，感受这段跨越时光、至今仍不断激发灵感的文化遗产。

Shakespeare Day

Each April 23, the curtain rises on the life and legacy of William Shakespeare, a playwright whose words still command the world's literary stage. Shakespeare Day commemorates the anniversary of his death in 1616 and the traditionally accepted date of his birth in 1564—a symbolic pairing that honors a writer whose works reshaped English literature. From the psychological depths of 'Hamlet' to the enduring romance of 'Romeo and Juliet,' his language continues to echo through classrooms, theaters, and everyday speech. His plays have been performed in numerous languages worldwide.

Today's image shows Anne Hathaway's cottage in Stratford‑upon‑Avon, England, the childhood home of Shakespeare's future wife. This 15th-century thatched cottage, now preserved as a museum, offers a rare glimpse into the domestic world that surrounded the young playwright. Visitors can explore original features, centuries‑old furnishings, and gardens inspired by Tudor life—an evocative setting in which to reflect on a legacy that continues to inspire new generations.

行动的力量 The power of protest

世界地球日

地球日从不是轻轻敲门，而是一次将大门猛然推开的觉醒。1970年，沾满石油的海滩、燃烧的河流与充满毒素的空气，让数百万人走上街头抗议。当人们再也无法视而不见，环境保护被推上政治议程，催生出一系列里程碑式的环保法案，也让“守护地球”从边缘议题跃升为全球共识。每年4月22日，全球190多个国家都会在这一天停下脚步，反思、审视，并重新思考我们与地球的关系。

2026年的主题“我们的力量，我们的星球”（Our Power, Our Planet）提出了一个雄心勃勃的目标：到2030年，将全球可再生能源产能提升至三倍。但真正的行动，不仅关乎风力涡轮与太阳能板，也在于守护那些早已默默运转的“自然引擎”。例如图中的爱沙尼亚塔尔图县阿拉姆-佩德亚自然保护区。自1994年以来，这里一直守护着欧洲最大的湿地系统之一。而它的方式，其实很简单——让自然顺其本来。河流自由流淌，泥炭沼泽悄然储存碳汇，洪泛平原吸纳多余水量，无需人工筑坝干预。驼鹿、猞猁与黑鹳在这里自在栖息，四季更替不断重绘这片土地的边界。阿拉姆-佩德亚告诉我们：有时候，最有力的行动不是干预，而是克制——退后一步，让自然引领方向。

Earth Day

Earth Day didn't knock gently. It kicked the door wide open. In 1970, oil‑soaked beaches, burning rivers, and toxic air mobilized millions into street protests. When looking away was no longer an option, conservation was forced onto political agendas, sparking landmark environmental laws and flipping planet‑care from fringe concern to global priority. Every April 22, over 190 countries pause, reflect, and reassess.

The 2026 theme, 'Our Power, Our Planet,' sets an ambitious target: triple renewable energy capacity worldwide by 2030. But action isn't only about turbines and solar panels. It's also protecting the natural engines already doing heavy lifting. Take Alam‑Pedja Nature Reserve in Estonia, captured here. Since 1994, it has safeguarded one of Europe's largest wetland systems. How? By letting it be. Rivers run freely, bogs store carbon, and floodplains soak excess water without concrete barriers. Elk, lynx, and black storks thrive as seasons redraw the map. Alam‑Pedja teaches that restraint can be the boldest move—to step back and let nature lead the way.

日落之后，探索仍在继续 The adventure doesn't end at sundown

峡谷地国家公园

国家公园周，是你暂别日常、走向自然的最佳契机。这一为期九天的庆祝活动将于4月18日至26日举行，聚焦国家公园体系中400多处自然与文化遗产地。在这里，自然风光与人文历史交织，为人们带来难忘的户外体验。从海岸线与森林，到辽阔的沙漠景观，这些受保护的区域邀请人们走进自然，感受宁静，心怀敬畏。

在美国犹他州东南部，靠近莫阿布的峡谷地国家公园，则提醒人们：冒险并不会在日落时结束。当最后一缕阳光隐去，科罗拉多河与格林河在深邃的峡谷间蜿蜒流淌，穿行于高耸的孤峰与嶙峋的岩柱之间。由于地处偏远、光污染极少，这里的夜空清澈通透，繁星如幕，令人叹为观止。

作为“国际暗夜天空公园”，峡谷地国家公园是体验沙漠夜晚的理想之地。在这里观星，无需深入荒野腹地——只需短途步行或在观景点驻足，便能收获难忘的夜间景致。尤其是在无月之夜，银河横贯天际，璀璨壮丽。

National Park Week

National Park Week is your cue to trade routine for trail dust. It's a nine-day celebration running April 18–26, highlighting more than 400 places across the National Park System that preserve natural and cultural heritage while creating unforgettable outdoor experiences. From coastlines and forests to vast desert landscapes, these protected sites invite exploration, reflection, and wonder.

In southeastern Utah, Canyonlands National Park near Moab offers a striking reminder that the adventure doesn't end at sundown. As the last light fades, the Colorado and Green rivers trace their way through carved canyons, towering buttes, and rugged spires. With its remote setting and minimal light pollution, the park's clear skies reveal a brilliant canopy of stars.

Designated an International Dark Sky Park, Canyonlands is one of the best places to experience the desert after dark. Stargazing here doesn't require heading deep into the backcountry—short walks and scenic pullouts provide unforgettable nighttime views, especially on moonless nights when the Milky Way stretches across the sky.

潮汐留下的印记 The tide's passing signature

巴西巴伊亚州塞古罗港 · 镜面海滩

从空中俯瞰，巴西的镜面海滩宛如一幅可以走入其中的水彩画。浅色的悬崖、点缀在海岸线上的礁石，以及由潮汐形成的片片水潭，在退潮时清晰映出天空与云朵，也正因如此，这片海滩得名“镜面海滩”。它位于巴西东北部大西洋沿岸的巴伊亚州，坐落在塞古罗港的几座小渔村之间。通往这里需要经过土路和短途步道，这种相对不便的交通反而成为一种“天然限流”，让海滩始终保持着宁静而私密的氛围。它位于巴西东北部大西洋沿岸的巴伊亚州，坐落在塞古罗港的几座小渔村之间。通往这里需要经过土路和短途步道，这种相对不便的交通反而成为一种“天然限流”，让海滩始终保持着宁静而私密的氛围。

最迷人的地方在于，这里的景观从不一成不变，而是始终与海洋进行着动态的“对话”。每一次潮汐都会重新勾勒沙洲的轮廓，显露出珊瑚结构，并为水潭补充新的“小居民”——鱼类、海星以及各种微小的海洋生物。最迷人的地方在于，这里的景观从不一成不变，而是始终与海洋进行着动态的“对话”。每一次潮汐都会重新勾勒沙洲的轮廓，显露出珊瑚结构，并为水潭补充新的“小居民”——鱼类、海星以及各种微小的海洋生物。

未完成巨像的静默 The silence of unfinished giants

世界遗产日

在今天的世界遗产日，人们将目光投向那些讲述人类共同历史的地方——这些地点因其卓越的文化或自然价值而受到保护。其中之一，便矗立在智利复活节岛的火山岩之上。在拉诺拉拉库，一座已熄灭火山的山坡曾是岛上绝大多数著名摩艾石像的雕刻工坊。画面展现的正是这一非凡的采石场：半成品的巨像从岩石中显现，仿佛在创作的瞬间被定格。

这些石像由拉帕努伊人在约13世纪至16世纪间雕刻而成，直接取材于压实的火山灰岩。完成后，它们被运往岛上的祭祀平台，用于宗教与仪式活动。拉诺拉拉库位于拉帕努伊国家公园之内，该公园被列入联合国教科文组织世界遗产名录，以其独特的考古景观和延续至今的波利尼西亚文化而闻名。

世界遗产日提醒我们，保护这些地方的重要性。像拉诺拉拉库这样的遗址，不仅仅是地标，更是人类智慧、信仰以及与土地之间联系的见证。这些珍贵的遗产被保存下来，让后代得以继续研究与感受。

World Heritage Day

Today, on World Heritage Day, attention turns to places that tell humanity's shared story—protected for their exceptional cultural or natural value. One of them rises from volcanic stone on Easter Island, Chile. At Rano Raraku, the slopes of an extinct volcano became the workshop where nearly all of the island's famous moai were carved. The image captures this remarkable quarry, where half-finished figures emerge from the rock, frozen mid-creation.

Carved by the Rapa Nui people between about the 13th and 16th centuries, the statues were shaped directly from compressed volcanic ash, then transported across the island to ceremonial platforms. Rano Raraku lies within Rapa Nui National Park, a UNESCO World Heritage Site recognized for its extraordinary archaeological landscape and living Polynesian heritage.

World Heritage Day highlights why protecting such places matters. Sites like Rano Raraku are more than landmarks—they are records of human ingenuity, belief, and connection to the land, preserved for future generations to study and experience.

花瓣巡游 Petal parade

斯卡吉特谷郁金香节

每年春天，华盛顿州的斯卡吉特山谷都会变成一片色彩斑斓的花海，斯卡吉特山谷郁金香节在此欢庆花季的到来。整个四月，游客们可以漫步于郁金香花园和农田，欣赏成排盛开的郁金香，远眺群山美景。

这个节日并非局限于一个地点——它横跨整个山谷，邀请游客探索多个花园，每个花园都各具特色。有些花园注重精心设计的花卉布置，而另一些则展现了仍在运营的农场和广袤的田野。除了鲜花，这个节日还为游客提供艺术展览、适合家庭的活动以及在该地区举办的社区活动。

展览选址于一座废弃的石灰岩采石场，将梵高的画作转化为一个共享的实体空间，投影在高耸的石墙和地板上。参观者不再是退后观赏，而是穿梭于色彩、韵律和尺度之间，体验科技如何重塑我们欣赏艺术的方式。这恰如其分地体现了世界艺术日的宗旨：不仅在于致敬艺术杰作，更在于重新思考艺术如何存在、发展并持续吸引新的观众。

Skagit Valley Tulip Festival

Each spring, Washington's Skagit Valley transforms into a patchwork of color as the Skagit Valley Tulip Festival celebrates the arrival of bloom season. Throughout April, visitors can explore tulip gardens and farmland lined with vibrant rows of flowers, all framed by mountain views.

The festival isn't limited to one location—it stretches across the valley, inviting guests to discover multiple gardens, each offering its own experience. Some focus on carefully designed displays, while others highlight working farms and wide- open fields. Alongside the flowers, the festival connects visitors with art exhibits, family-friendly activities, and community events hosted throughout the region.

Bloom timing changes every year, making each visit a little different, so checking bloom updates is part of the adventure. What began as a small local celebration in 1984 has grown into one of the Pacific Northwest's most loved spring traditions, drawing photographers, nature lovers, and road trip enthusiasts eager to welcome the season.
