The Portland Museum of Art placed the Robert Indiana sculpture “Seven” in front of the museum Monday morning. The steel sculpture, which announces the museum’s presence at 7 Congress Square, will be celebrated at 5:30 p.m. Friday as part of the city’s First Friday Art Walk.

Indiana, 86, lives on Vinalhaven off Rockland. “This is a public announcement that 7 Congress Square will always be a place for art,” said chief curator Jessica May. She called Indiana “one of the state’s most beloved artists,” and said placing art outside the museum is part of a larger effort to engage with the public whenever possible.
