Protestantse Kerk
Sirjansland, NL
In 1956, a new Mennonite Church was built in Amsterdam-Slotermeer at Arthur van Schendelstraat 17. The building was designed by Karel Sijmons. In 1957, Willem van Leeuwen installed a new organ in this church with two keyboards and sixteen registers. In 1969, the church building was sold to the Reformed Church Slotervaart/Osdorp, who took over the building including the organ. It was then named De Olijftak. In 1993, the church was closed for worship. The organ was sold to the Reformed Church in Sirjansland in 1996. De Olijftak has been in use as a Moroccan mosque since 2000. The organ was moved to Sirjansland by the firm Pels & Van Leeuwen. The organ was put into use on 11 February 1996. The organ was not changed during the move. However, the front was decorated with several wooden ornaments.
