Originally named Constantia and constructed as a Headquarters, the building was bought over and converted into a Church by a Jesuit church community called “The Sower” in 1899 and renamed The Saint Joseph’s Chapel. After once flourishing as a Church, the community declined steadily, particularly after the Second World War leading to the closure of the church in 1971.

In 1981 the building was bought by a Turkish-Dutch community and converted into the “Fatih Mosque”. The conversion entailed one major transformation: the former church entrance was closed and replaced by a prayer wall, in order for the Muslim community to be able to pray in the direction of Makkah.

The former church building was in a state of decay. The Fatih Musjid community decided to renovate the building thoroughly. In 2001, it was listed as a monument by the City Council, and the roof and towers were restored. The Musjid community constructed a new and more prominent entrance, intended to make the Musjid more visible and recognizable from the street. This will allowed the Fatih Musjid to become visible as an important, and indeed the largest, Musjid in Amsterdam.
