Collegiate Church of St. Peter and St. Guido

The Collegiate Church of St. Peter and St. Guido is a Catholic collegiate church located in the centre of Anderlecht, a municipality of Brussels, Belgium. It is dedicated to Saint Peter and Saint Guy, the patron saint of Anderlecht.

The church, in Brabantine Gothic style, was built between the 14th and 16th centuries above an earlier Romanesque crypt. Partially attributed to the Flemish architect Jan van Ruysbroeck, it is a notable illustration of late medieval architecture in Brussels. Its neo-Gothic spire dates from the 19th century. The complex was designated a historic monument in 1938.
