The Deutsche Stiftung Denkmalschutz ("German Foundation for Monument Protection") is a German private initiative founded in 1985[1] that works for the preservation of cultural heritage in Germany and to promote the idea of cultural heritage management.
Denkmalschutz works to coordinate efforts, promote public awareness, and also to act as a central contact for worldwide organizations such as UNESCO World Heritage.
They also organize and fund the European Heritage Days in Germany, which are called Tag des offenen Denkmals.
This "open monument day" has been held yearly with a different theme since 1993 on the second Sunday of September.
Many sites are marked with a tag according to the Hague Convention of 1954 regarding the protection of cultural heritage in times of armed conflict.
