Sewer Museum

Sewer Museum in Brussels is one of the Belgian capital's most unusual attractions — a museum dedicated entirely to the city's sewage system. It opened in 1988, and ever since it has given visitors the chance to descend beneath the streets of Brussels and see, firsthand, infrastructure that normally stays completely out of sight.

What can you see inside?

The museum's centerpiece is a walk along a 50-meter stretch of an actual sewer tunnel. Visitors move above a working installation, with liquid sewage running below their feet — making this one of the most literal ways to experience a city's underground infrastructure. It's a very different kind of visit from a typical museum tour, engaging more than just sight.

Why visit the Sewer Museum?

This is a destination for travelers looking for something beyond Brussels' usual highlights — the Grote Markt, the Atomium, or Manneken Pis. Instead of another exhibition on art or political history, it offers a look at the city from an angle most residents and tourists rarely consider: the system that carries wastewater away and keeps a major city functioning. It's a kind of industrial curiosity that appeals to people interested in urban engineering, the history of infrastructure, and offbeat, slightly grittier attractions that fall outside the standard tourist circuit.

What to expect

Visitors should be prepared for a noticeable, unpleasant smell — a natural consequence of being close to a working sewer system and part of what makes the experience so authentic. It's not an attraction for anyone sensitive to strong sensory experiences, but that rawness and authenticity are exactly what set it apart from the capital's other museums.
