Originally the main terminal and control tower of San José’s first international airport, this museum houses the largest and most important collection of works by Costa Rican artists from the colonial time to the present. The museum’s permanent collection has over 6,000 pieces, including works by big names like Juan Manuel Sánchez, Max Jiménez, Francisco Amighetti, Lola Fernández, and more. There’s a sizeable collection of Amighetti’s stark and minimalistic lithographs, and 19th-century oil paintings of classic rural country scene’s like “El Portón Rojo (The Red Door)” by Teodorico Quiros. On the back patio—which used to lead to the tarmac—is a sculpture garden. This museum  anchors the eastern edge of La Sabana city park, making it easy to combine a visit here with a stroll through the park.
