It costs €8 to visit both this and the New Church - totally worthwhile! There’s a handout in many languages on both churches included with your admission and between that and the signage, everything is clear. The staff is very helpful and the gift shop is small but quite nice.

The leaning tower of Oude Kerk is an eye-catching landmark of Delft. One of the tallest structures of the city, it can be seen anywhere around the historic city center. Entrance requires admission.

The Oude Kerk is, naturally, an old church located in the center of Delft. We visited in April 2023. Parts of the church date from the 13th century, and at this time the interior is a brilliant painted white with beautiful stained glass windows. Displays spread throughout the interior describe aspects of the church’s architecture and history along with notable individuals from Delft. Numerous people are buried in the church, including Johannes Vermeer and Anthony van Leeuwenhoek, many with carved tombstones. When we visited there was also a separate display of paintings from a contemporary Dutch artist, Henk Helmantel, who paints modern still lifes. As many others have noted, one may purchase a single ticket to enter both the Old and New churches in Delft. The church was busy when we visited, but there was plenty of space for people to spread around. Amenities included restrooms and a gift shop. There were no issues with taking photographs. Highly recommended for lovers of history and art and old churches. An hour or less is probably sufficient time to visit the church.
