In 1980s, the current owner of the site made an inadvertent archaeological discovery while attempting to restore this Italian-style house, whose façade and patios date back to the first half of the 19th century. As a result of the excavations, the remains of tunnels that once channeled the Zanjón de Granados, cisterns, water tanks, utensils, containers, and remains of buildings from 1700, 1740, and 1830 were recovered beneath the mansion and adjacent buildings.

Glad we went

The tour was well-done and very interesting. It was a small group so it was a great break from the tourist crowds while being entertained and educated on the area’s history.

Constructive criticism

A nice experience. Only you have to be on time, because the guide begins without taking into account that if they are all or if someone is missing to arrive.

Beyond expectations. If you have one day only see this one

Strongly recommend to visit. Excellent presentation, display and museum are informative and demonstrate a great way to understand this unique archeological exhibit. Beyond our group expectations. If you go on a Saturday or Sunday you get to enjoy the neighborhood and art and crafts fair
