The Church of Saint-Lambert has an unconventional orientation due to its location along the Black Water: instead of being oriented from east to west, it is oriented almost from north to south.
This church in neoclassical style was built between 1829 and 1830 according to plans by architect Jean Kuypers. It replaces an older church built on a different site; on the hill of Mousty.
The church has 3 naves, separated by 2 rows of 5 square columns. The central one is covered with a barrel vault (the face of the arch has a constant curvature). It houses a pulpit from 1769.
Each corridor (side parts of the nave) ends with an altar in Baroque style. They probably date from the 19th century. The altar table is made of red marble. The altarpieces (carved or painted vertical structures) are white and gilded. They are decorated with a statue and a painting.
The apse is semicircular and pierced with 3 oculi (round openings).
The choir contains a rough stone altar from the 20th century.
The main altar has a Baroque style. It is an almost replica of the 2 side altars (red and black marble table and white and gilded altarpiece).
The globe surmounted by a cross symbolizes the rule of the Judeo-Christian God over the world.
