Free for All
The headline of the annual Opening Our Doors celebration is free admission to the Museum of Fine Arts and the Isabella Stewart Gardner Museum, but keep reading — the Fenway Alliance goes all-out for a day of art installations and cultural experiences across the neighborhood. Just a stroll or free trolley ride away are live music, an interactive community mural, and more. 10 a.m. to 4 p.m. (later at some venues). Free. fenwayculture.org
