Westerkerk (Western Church) is a Dutch Protestant church in central Amsterdam in the Netherlands. It is next to Amsterdam's Jordaan district, on the bank of the Prinsengracht canal.
The tower, called the Westertoren ("Western tower"), is the highest church tower in Amsterdam, at 87 meters (±286 feet). It is not known who the designer of the spire was. Hendrick de Keyser designed an octagonal spire for the tower which was never build. It is suggested Jacob van Campen was the designer. The crown topping the spire is the Imperial Crown of Austria of Maximilian I.
Rembrandt van Rijn was buried somewhere under a tombstone in the Westerkerk on October 8, 1669. The exact location of the grave is unknown; the number of his grave was lost. It was in a numbered grave owned by the church.
The Westerkerk is located close to the Anne Frank House where diarist Anne Frank, her family and others were hid in the 'Achterhuis' from Nazi persecution for two years during World War II. The Westertoren is mentioned frequently in her diary - its clock-face on the tower could be seen from the attic of the Achterhuis and Anne Frank described the chiming of the carillon as a source of comfort. A memorial statue of Anne Frank is located outside the church at Westermarkt.
