The spire, called the Westertoren ("western tower"), is the highest church tower in Amsterdam, at 85 meters (279 feet). The crown topping the spire is the Imperial Crown of Austria of Maximilian I. The church bells were made by François Hemony in 1648.
Rembrandt van Rijn was buried in the Westerkerk on October 8, 1669. The exact location of the grave is unknown, but presumed to be somewhere along the northern wall. Rembrandt's lover Hendrickje Stoffels is also buried here, as is Rembrandt's son Titus van Rijn. Other painters buried in the Westerkerk are Nicolaes Berchem, Gillis d'Hondecoeter, Melchior d'Hondecoeter and Govert Flinck. The church organ is decorated with doors painted by Gerard de Lairesse.
