St. Michael and St. Gudula Cathedral is a Gothic cathedral. The church was built in 1047 and was built on the original St. Michel Chapel. The grand expansion of the church began in 1226 and lasted for two and a half centuries. The St. Michael and St. Gudula Cathedral is not too complex, it retains the simple lines of Gothic architecture and is very atmospheric. There are two symmetrical towers on the façade of the church, using a rare flame-style Gothic style with simple and sturdy reliefs.
