The iconic Dutch Reformed church in Amsterdam, designed by Hendrick de Keyser in 1620 and boasting the largest nave in the Netherlands, is a popular gathering place for the city's Protestant community. Its wooden barrel vault covers the interior of the space, which houses the impressive main organ from 1686. Embellished with a variety of instruments and scenes from the Bible, the organ is a sight to behold. Although Rembrandt (1606-69) is well-known for his works of art, the Dutch master is also famously remembered as having been buried in an unmarked, pauper's grave somewhere in the Church. Visitors can ascend the bell tower for an even better view of the Church and its architecture.
