It’s one of the main cultural attractions in Washington, DC.

But The Smithsonian Institution is closing parts of three museums because of mandatory budget cuts imposed by the federal government.

The Hirshhorn, The National Museum of African Art, and Smithsonian will close their doors until September 30th.

Parts of the museums will gradually go dark as exhibits come to their scheduled end. Instead of replacing them, they will keep the spaces empty to reduce security costs.

The museums will be closing down just as the Smithsonian usually welcomes some of its biggest crowds.

The closures have been made necessary because of the ongoing budget deadlock in the US congress.
