Once upon a time, El Museo de Arte Costarricense (MAC) was Costa Rica's main airport terminal. Now it is home to a diverse collection of works by some of the country's most revered artists and serves as a celebration of national talent. Upstairs, a bas-relief on the walls of a conference room tells the story of Costa Rica, and an outdoor sculpture garden is a delightful addition to the permanent collection of painting and prints within. Though it's small, one can spend hours exploring. Rotating exhibition and special shows by visiting artists keep things fresh year-round. Find it next to the Sabana Metropolitan Park, a lovely place for a stroll.
