This house was built by the Mustelier family, of French origin, in 1739. It is a magnificent example of 18th century domestic architecture, with a central linteled doorway topped by a peculiar mixtilinear pediment which contains two inscriptions. The inscription “I.H.S. 1739” represents the symbol or monogram of Jesus Christ accompanied by the year the house was erected, and “Ave Maria S.P.C.”, which means “conceived without sin”.
On both sides, on the second floor, the traditional sash windows stand out, providing symmetry to the group.
