Sewer Museum

The Sewer Museum (French: Musée des Égouts; Dutch: Riolenmuseum) is a museum in Brussels, Belgium, dedicated to the city's sewage system. Opened in 1988, the museum allows visitors to walk along a 50-meter stretch of a sewer tunnel. It has a noticeable stench, and liquid sewage runs below visitors' feet.

The museum presents the history of sewage including the Senne river being moved underground in the 19th century, environmental concerns regarding sewage, and the work of égoutiers, or sewer workers, who work in underground sewage tunnels. Its entrance is located at the Anderlecht Gate, in a neoclassical former octroi pavilion designed by Auguste Payen.
