At the Onze Lieve Vrouweplein (Square of Our Dear Lady) in Maastricht you find the Basilica of Our Dear Lady. This Roman style church has a turbulent history and has even served as a horse stable and a cannon forge.
Walk in when your around and admire the organ that has been in place since 1652 and the church treasure made up out of silver, ivory and velvet containers of religious artifacts.
The church being in such good state today is due to the pope elevating the church to basilica minor.
