Fodor's Expert Review Montelbaanstoren

Rembrandt loved to sketch this slightly leaning redbrick tower, which was built in 1516 as part of the city's defenses. In 1606, the Dutch sculptor and architect Hendrick de Keyser oversaw the addition of an octagonal brick superstructure and spire complete with clockworks that was known as Malle Jaap (Crazy Jaap) by locals because the bells pealed at odd times. The year 1610 saw the tower embark on a lean too far, and with lots of manpower and ropes it was reset on a stronger foundation. From 1878 to 2006, it housed the City Water Office. Today it's the office of a company that rents out classic saloon boats (captain included).
