Just to the south of the Markt is Sint Janskerk. The church itself had chequered beginnings: it burned down with ungodly regularity every 100 years or so from 1361 until the mid-16th century, when what you see today was completed. At 123m it is the longest church in the country because the ground was so soggy it couldn't support the weight of a tall structure. An audioguide in English costs €2.
Its huge windows set it apart, especially those created by Dirck Crabeth, his brother Wouter, and Lambert van Noort from around 1550 to 1570. Their works, which are numbered, include highlights such as window No 6 (John the Baptist; the folks on either side paid for the window) and No 22 (Jesus purifies the temple; note the look on the face of the moneychanger).
