The church was dedicated to Saint Nicholas, considered one of the patron saints of the whole city. You might know Saint Nicholas by his more well-known nickname, Santa Clause...
At the front of the building is the Rossetta window, whose center is designed as a flat plate that shows Jesus and his four Apostles. The window was created in 1886 by Van den Bossche, and his team of workers. Above the window is the holy statue that protects the church and Amsterdam. The statue was sculpted by Bart van Hove in 1886.
The main alter of the church describes the miracle of the half-digested bread, which was the most important religious event to happen in the city, and above it is the crown of Emperor Maximilian I. In the church walls you can see murals.
The church received its status as a basilica in 2012.
