Every year, since 1982, the 18th of April is celebrated as the International Day for Monuments and Sites (IDMS). 18 April represents an opportunity for all ICOMOS Committees – and indeed the entire ICOMOS network – to advocate for and celebrate cultural heritage together. This ICOMOS project was later adopted by UNESCO and is an opportunity for the ICOMOS network and other heritage professionals and lovers to come together for their shared cause. Today, on the International Day for Monuments and Sites, you can take part in a wide range of physical and online activities celebrating cultural heritage, raising awareness and advocating for conservation.
Every year, the International Day for Monuments and Sites has a different theme, but ICOMOS members remain free to choose the theme that is most relevant for highlighting heritage issues in their nation or region.
What is essential is to make the 18th of April not only a day for celebrating your local and national heritage, but also a day of international solidarity, to strengthen and safeguard cultural heritage around the world.
Organised by the ICOMOS National Committee and its Scientific and Regional Committees, these can bring attention to local sites and issues, and develop support in the community, as well as with authorities and experts.
This can take various forms and appear in different media, including:
ICOMOS believes events are a great way to attract attention and focus. They can take many forms, including:
If you are planning an event linked to 18 April or to the current year’s theme, please get in touch with ICOMOS Headquarters to let them know as soon as you have the opportunity.
ICOMOS has always sought ways of promoting and celebrating cultural heritage. While many countries and regions have established heritage days and events, like the European Heritage Days every September, no such day existed on a worldwide scale.
During an ICOMOS Tunisia symposium and bureau meeting in Hammamet on the 18th of April, 1982, the idea of establishing a day every year to celebrate heritage worldwide was suggested. This developed into the International Day for Monuments and Sites, with the Board of ICOMOS approving the project and giving practical advice to the ICOMOS network on how to organise 18 April celebrations.
April 18th gained in stature with the UNESCO General Conference adopting the concept during their 22nd session in 1983.
In 2001, ICOMOS President Michael Petzet and the Board of ICOMOS proposed that April 18th be used by all ICOMOS Committees to draw attention to a particularly endangered type of cultural heritage. Since then, a growing number of Committees hold special events on the 18th of April every year, as International Day for Monuments and Sites becomes an increasingly prominent part of the cultural calendar.
