What remains of a street lodge
Built at the end of the sixteenth century by the Gujo i Durant family, originally from Tortosa and among the wealthiest of the city's oligarchy, the palace owes its current name to the Perretti family, who came from Corsica, and purchased it in the seventeenth century. It is a typical portico building, as evidenced by the external portico, now walled up, on the façade on Via Roma, with three double ring arches and a lowered arch. On the same façade, on the upper level, there were two mullioned windows on columns, later closed in favor of the current openings. Above one of them a rosette star (or six-petalled flower) is engraved: a decorative element which is also recognizable in some mullioned windows discovered in via Maiorca. The small windows on the mezzanine floor, the windows and balconies on the second and third levels are the result of contemporary renovations, carried out at various times. The raising of a floor dates back to 1953.
The rooms on the ground floor, where the external portico is located, housed the merchants' homes and offices, and hosted the storage and sale of goods. The porticales buildings were in fact typical of the mercantile areas of the Aragonese Mediterranean. Similar examples are Casa Farris and Casa Guarino in Sassari, and the Dogana Reale, in Piazza Civica, in Alghero itself.
The presence of the porticals in the façade, as well as in the internal loggias, around the uncovered patios, testifies to the city's link with other port and mercantile areas and, in particular, with Genoa, where this type of space management was already in use, and with Palma de Mallorca, where the comparison with the loggia patio of Can Bordils, now home to the Municipal Archives, is immediate.
