The oldest church in Delft, begun in 1246, stands at a noticeably crooked angle thanks to the subsidence that afflicts all of Delft's old buildings — the leaning tower earned the church the nickname Scheve Jan (Skewed John). Inside, the scale is impressive: a long Gothic nave with 27 stained-glass windows and a choir screen of elaborately carved stone.
The church is also a significant burial ground. Vermeer's grave is here, a simple floor stone marking the resting place of the city's most famous painter. Antonie van Leeuwenhoek, the inventor of the microscope who lived his whole life in Delft, is buried nearby. The combination of the leaning exterior, the medieval interior, and the historic graves makes this one of the most rewarding churches in the Netherlands. Small admission charge.
