The Cathedral of Saint Bavo seems to be the main cathedral of the city of Haarlem, the Netherlands. It is located right at the heart of the center of the city, Grote Markt. The cathedral looks quite massive and medieval, but surprisingly it was built in 1930, less than 100 years old. There was a church in the same site all the way back from the late 7th century as the primary church of the town as it is located right by the market square. The church has tumultuous history converting back and both between a protestant church and a catholic cathedral over the past 500 years.
