International Day for Monuments and Sites Apr. 18, 2025

International Day for Monuments and Sites

Imagine a world without the pyramids, the Great Wall or ancient cave cities—hard to picture, right? That"s why April 18 is the International Day for Monuments and Sites, an event recognised by UNESCO dedicated to protecting cultural treasures worldwide. This day is all about celebrating our history, raising awareness about endangered sites and making sure future generations can enjoy them too.
