On the other side of the square from the Museum of Guamuhaya Archeology is the House of the Sánchez Iznaga ("Casa de los Sánchez Iznaga") which houses the Museum of Colonial Architecture ("Museo de Arquitectura Colonial"). This building was originally two houses in the 18th century, both owned by the sugar barons of the Sánchez Iznaga family (who owned the Manaca Iznaga estate in the nearby Valley de los Ingenios). The two houses, joined in the 19th century, show the typical grilled and shuttered windows, and feature an elegant portico with slim columns and a delicate wrought-iron balustrade, in contrast to the heavier pillars and ironwork of the Museum of Guamuhaya Archaeology on the other side of the square. Inside, the museum features items from Trinidad's architectural history (including an elaborate 19th-century shower) and details the history of building in the Colonial period.
