Beemster Keyserkerk
Three years after reclamation, the polder board, at the time largely composed of prominent Amsterdammers, appointed the master builder Hendrick de Keyser to design a church for the Beemster.
A new building form, a rectangular hall church in Renaissance style, was chosen for the new polder. Construction of the church in Middenbeemster began in 1618. It is one of the earliest examples of Protestant church construction in Holland following a traditional longitudinal pattern.
After the tower was completed in 1621, the church could be consecrated on 30 July 1623. The design was by Hendrick de Keyser, assisted by his executor Cornelisz. Danckerts. In 1625, two rooms were built on either side of the tower, the current consistory room and the stove room. The slender tower in could also serve as a lookout in case of (fire) danger. The new extension on the south side was built in 2012.
