A public toilet transformed into an art museum is Munich’s newest tourist attraction, CBC News reports.

According to a spokesperson from the city’s tourism authority, the temporary, 750-square-foot exhibition space has attracted hundreds of people in the first days after opening.

Built in 1894, the toilet originally served nearby households. It remained in use for nearly a century, before being closed in 1992.

Mathias Koehler, who initiated the project, explained that a toilet was a great place for artistic expression because art is a form of relief. He also indicated that he would not rule out making the museum permanent if public interest remains high.

The toilet museum’s inaugural exhibition contains mostly graffiti, much of it with political themes. Four artists contributed to the show, which contains, for example, images of Barack Obama and German Chancellor Angela Merkel.
