Dating back four centuries, this lively plaza features fairs and exhibitions, and includes a statue of its namesake, General San Martin, a colonial-style cathedral and a 17th-century cabildo, or clubhouse, once used as a police headquarters.

Beautiful inside and out, with Indian angels gracing its towers, this cathedral at Plaza San Martin was started in 1577 and took almost 200 years to build.

Cordoba’s first Spanish governor lived and worked in this spacious colonial house, which is filled with furniture, rifles, saddles, military uniforms and other 18th-century artifacts.
