Juan Santamaría Museum, National history museum in Alajuela, Costa Rica.
The Juan Santamaría Museum occupies the former Cuartel de Armas and the old Alajuela jail, two 19th-century buildings listed as national heritage for their Neoclassical architecture. Its rooms hold documents, books, newspapers, genealogies, coins, artworks and the uniforms worn during the 1856-1857 campaign. The photograph shows a framed painting of a standing man in a light shirt and dark cap reaching toward a dark draped panel.
The museum was created in 1974 to preserve the story of 1856-1857, when the region fought against William Walker's armed forces. That period proved crucial in shaping Costa Rica's independent path and future stability.
The museum is named after Juan Santamaría, a local hero whose story shapes how people here understand their past. Walking through the rooms, you can see how this shared history connects visitors to the broader story of Costa Rican independence.
The museum sits on Avenida 1 between Calles Central and 2 in the city center and is easy to reach on foot. Plan to spend a few hours walking through the different rooms at your own pace.
The museum displays uniforms worn during the 1856-1857 National Campaign, alongside paintings, coins and genealogical documents. Its collection also covers general Costa Rican history, biography and art, so the military rooms are only part of what the former Cuartel de Armas and Alajuela jail now hold.
