Alcázar de San Juan has several prehistoric sites outside the purely urban area, such as La Motilla de los Romeros and the Cabaña de las Saladillas site in the surroundings of the lagoons, both from the Bronze Age, or the more recent Chalcolithic and Iberian remains found in the area of Piedrola. In 2014 a Muslim necropolis was discovered here, and in 2015 what appears to be a Roman villa was found.
It also has archaeological remains of the Roman Villa located in the urban center of Alcázar, which can be seen next to the Palace Chapel.
