The Jesuits have overgrown a large piece of De Ruien to make room for the beautiful St. Charles Borromeo Church on the Hendrik Conscienceplein. This beautiful baroque church, in addition to its magnificent treasures and works of art, praises some of its underground secrets including a visit to the ancient crypts. After visiting this baroque church par excellence, you can descend to the cellars to gain access to De Ruien via a rediscovered door.
