The Archaeological and Ethnological Museum of Córdoba is a museum in the city of Córdoba, Andalusia. The Archaeological Museum was formally established by an initiative proposed in 1866 and by the subsequent decree for the creation of the provincial museums of March 20, 1867. The museum was integrated with the Museum of Fine Arts, but subsequently many efforts were made to ensure that this the latter could have an independent seat for the growing collection of archaeological finds. The Spanish state bought the Renaissance palace of Páez de Castillejo in 1942 to make it the new home of the museum. Work on the adaptation ended in 1959. The museum took its current name in 1994 and in 2011 a new annex was opened. In its collection, the museum incorporates its own archaeological site, with the remains of the city's Roman theater.
