This large church in the centre of the town, next to the casino and the baths, only dates from 1885 but as it is in Rhenish Neo Romanesque style, it gives the impression of being much older. It is built with a unique Ardennes stone.
Inside, there are several carved or painted works worth seeing: the high altar, the pulpit, a high relief of angels in the right transept, six beautiful wooden statues of saints in the upper part of the central nave and various paintings. The church also has a new organ which blends harmoniously with the other fixtures.
Queen Marie-Henriette, King Leopold II’s consort, who stayed many times in Spa donated the stained glass window in the left transept. She went to Mass here every Sunday and her funeral was here in 1902.
