This evolving collection turns the spotlight on spaces that Muslims in Europe have created for themselves since the beginning of the 20th century. The collection includes structures established by local Muslim communities--mosques, cultural centers, cemeteries, and even interfaith centers, in countries where Muslims are not a majority. The omission of sites in countries with a large Muslim population is not intended to imply anything about what it means to be European. Rather it is to keep the focus on the architectural manifestations of minority communities. In this sense this collection is a companion to the Mosques of North America collection.
