The "New Church" — new only in the sense that it was begun in 1381, a century after the Oude Kerk — dominates the Markt with its 108-metre tower, the second tallest in the Netherlands. The tower leans slightly (the soft Delft clay gives way under heavy foundations) and offers remarkable views over the city and toward The Hague and Rotterdam from its observation deck.
Inside, the white marble mausoleum of William of Orange is the centrepiece: a magnificent Renaissance monument with a bronze effigy of the Prince lying in full armour, his dog at his feet. The Dutch royal family continues to be interred in the crypt below. The church charges separate admission for the building and the tower. The tower climb is steep but the view justifies the effort.
