The Ciudad de Carmon Museum provides insight into the history of Carmona from its origins (a million years ago) to the present-day. It features archaeological remains from the Palaeolithic, Chalcolithic, Turdetan and Andalusí periods. However, the most important are the Tartessian (Saltillo Vessels), and Roman remains. Also noteworthy is the pictorial collection with works by J. Arpa, Rodríguez Jaldón or Valverde Lasarte.
In addition to the guided tour of the Ciudad de Carmona Museum, visitors can view documents about its heritage. Today, the Ciudad de Carmona Museum and Interpretation Centre is sited in a former 16th-century palace, the Casa del Marqués de las Torres. (Declared an Asset of Cultural Interest in 1983)
The Casa Palacio Marqués de las Torres is an example of Carmona’s palatial 18th-century architecture.
The date of construction of the palace appears on the pediment of its monumental stone façade -1755-, which also has engraved the coat of arms of the Quintanilla family.
The Islamic embellishments that decorate the balconies of the side façade are interesting. The central courtyard has a square floor plan, and the rooms are structured around the courtyard in two levels. The painting of Our Lady of Grace on the staircase is worthy of note, as is the glazed ceramic baptismal font from the 16th century.
