Outdoor sculptures often become iconic landmarks, but some of the most fascinating ones are only visible during specific times or seasons. These temporary or seasonal artworks captivate audiences with their fleeting presence, blending art with nature’s rhythms.

One remarkable example is *The Spiral Jetty* by Robert Smithson in Utah, USA. This massive earthwork sculpture, made of basalt rocks and mud, emerges from the Great Salt Lake when water levels drop, creating a stunning spiral visible only during dry periods.

In Italy, *The Floating Piers* by Christo and Jeanne-Claude allowed visitors to walk on water for just 16 days in 2016. The bright yellow walkways stretched across Lake Iseo, offering a once-in-a-lifetime experience before being dismantled.

Another ephemeral wonder is *Ice Watch* by Olafur Eliasson, where massive blocks of glacial ice were displayed in public squares, slowly melting to raise awareness about climate change. These installations appeared briefly in cities like London and Paris before vanishing.

Seasonal sculptures also include *The Sand Museum* in Tottori, Japan, where intricate sand artworks are created annually and last only a few months before being reclaimed by the elements.

These sculptures remind us of art’s transient beauty, inviting viewers to cherish moments when nature and creativity align. Whether due to weather, tides, or intentional design, their temporary visibility makes them even more extraordinary.
