The Day of Historic and Cultural Monuments is observed in Ukraine on April 18 every year, coinciding with UNESCO’s International Day for Monuments and Sites. Established by President Leonid Kuchma in 1999, this day celebrates Ukraine's rich array of historic and cultural sites, which include seven World Heritage Sites as of 2022, such as Saint Sophia Cathedral in Kyiv and Lviv’s Old Town. The Ministry of Culture and Information Policy, along with various cultural organizations, prioritizes the protection of these monuments. The observance serves as a professional holiday for architects, conservation professionals, and government employees involved in heritage preservation. The significance of this day was particularly highlighted in 2022 during the Russian invasion, which resulted in damage to numerous cultural sites across Ukraine.
