Palacio de Mon, Baroque palace in Samartín d'Ozcos, Spain.

Palacio de Mon is an irregular-plan palace arranged around a central courtyard in Mon, 5 km from the capital of San Martín de Oscos. Its south-facing main facade has a lower central body between two square towers; the southeast tower, of rough masonry, is the 16th-century core, while the rest was built in ashlar in the late 17th or 18th century. The upper floor holds a projecting iron-balustraded gallery and two large coats of arms, and the roofs are slate.

The palace was built in the 18th century as a residence for influential noble families involved in the economic life of Asturian territory. This period saw the construction of such grand homes as expressions of wealth and authority in the region.

The palace reflects how noble families shaped the architectural character of rural Asturian villages through their residences. These grand stone buildings served as visible symbols of social status within their communities.

The location is accessible via the regional road AS-27 through the municipality of Samartín d'Ozcos in western Asturias. Since it is protected cultural heritage, it is worth checking locally about access conditions and any restrictions before planning a visit.

The southeast tower is the oldest part, built of rough rubble masonry probably in the 16th century; the rest of the palace was added in dressed ashlar blocks at the end of the 17th or in the 18th century. The two materials remain visible side by side.
