Municipal Museum

The Municipal Museum of Alcázar de San Juan is housed in the former Posada de Santo Domingo, a 16th-century building that preserves the typical structure of La Mancha inns with its arcaded courtyard and wooden galleries. Its archaeology rooms offer a fascinating journey through the territory's history from Prehistory to Roman times, with highlights including polychrome mosaics from nearby villas, Iberian ceramics, coins and everyday objects found in local excavations. The upper floor hosts temporary contemporary art exhibitions that dialogue with the historical space, creating a stimulating contrast between past and present. Free admission and the careful museum design make this a must-stop for discovering Alcázar's deepest roots and the archaeological wealth of the La Mancha region.
