The Créteil Cathedral is a modern creation: in 2010, a distinctive architectural project was launched to rethink the site, the welcome for visitors, and its place in the landscape. In 2013, the old building was demolished and construction began. In 2015, the new cathedral was inaugurated and officially consecrated.

This place of worship is truly one of a kind: the interior is as stunning as the exterior. Don’t miss visiting this cathedral during your Heritage Days tours in the Val-de-Marne.
