Montelbaanstoren

The Montelbaanstoren is a tower on bank of the Oudeschans, Amsterdam canal in the Netherlands. The original tower was built in 1516 as part of the Walls of Amsterdam for the purpose of defending the city and the harbour. The top half, designed by Hendrick de Keyser, was extended to its current, decorative form in 1606. Since then the tower is 48m high.
