International Day of Monuments and Sites – Apr 18 & 19

Posted by Global Philadelphia on April 1, 2025

The aim of the International Day for Monuments and Sites is to encourage local communities and individuals throughout the world to consider the importance of cultural heritage to their lives, identities and communities, and to promote awareness of its diversity and vulnerability and the efforts required to protect and conserve it.

Philadelphia’s staggering 67 National Historic Landmarks are a testimony to the heft of our historical city and its international significance. Global Philadelphia has created an easily accessible map of the NHLs for tourism and heritage interests. The NHL community, consisting of the city’s 67 National Historic Landmarks, offers members, city residents, and tourists alike the opportunity to learn about cultural heritage and all of the hidden historic gems of our World Heritage City.

A community has taken root within the network of the 67 NHLs, with Global Philadelphia there to organize events, tours, SDG partnerships, and educational opportunities in our Learn Philly Heritage program. IDMS is a day for all of these NHLs to come together and acculturate the Philadelphia community and to be connected on this internationally celebrated day.

Last year, we had over 25 participating sites and this year we hope to have over 30 total participants, nearly half of the 67 NHLs. Don’t miss out on this opportunity to get involved with the community and enhance the visibility of your site!
