Sint-Theodarduskerk, church in Belgium

Sint-Theodarduskerk is a parish church in Beringen built between 1939 and 1943 by architect Henry Lacoste and known as a mine cathedral. The building features a single-nave cross design with red brick walls, a bell tower rising more than 71 meters, and ornamental brick patterns including a series of pointed arches on the exterior.

The Beringen coal mine's construction led to the factory settlement of Beringen-Mijn, and the church was built there from 1939 to 1943 to serve the new parish. Architect Henry Lacoste designed it as one of five mine cathedrals in Limburg. It received protected monument status in 1985.

The church is one of five mine cathedrals in Limburg, a term for the large parish churches built for coal-mining settlements. Its stained-glass windows were designed by architect Henry Lacoste: glass made at the Val Saint-Lambert crystal factory was set into reinforced concrete cast at the mine.

The church stands on Koolmijnlaan in Beringen-Mijn, with a pointed-arch gallery forming an atrium at the front and parish buildings grouped around a courtyard at the rear. The brick spire of the crossing tower reaches 71.5 metres. Visitors should note that the interior is generally shown by guided group visits arranged in advance, while the exterior can be walked around at any time.

During summer months the church is illuminated by the Cloisterrama art installation, where 68 pointed arches glow in 11 bright colors. This colorful light display highlights the architecture while symbolizing diversity and inclusion in a modern interpretation of the historic building.
