The Westerkerk church is a 17th century church, built as a Protestant church (and it is still used for church services).
It is one of the most beautiful buildings in the centre of Amsterdam, and with its tall tower it dominates the Jordaan district (and has become a symbol of it), right next to the Anne Frank House.

The church has a tower that you can climb, and inside there is a church organ which is sometimes played. There are frequently concerts in the church.

The crown on top of the tower is there because in 1489 Emperor Maximilian I of Austria granted Amsterdam the right to carry the crown in its weapon, in return for political and military support.

The church has a wonderful large organ, which is sometimes played.
