Tresnuraghes

Geography and Environment

Tresnuraghes is the most important center of the Planargia region after Bosa, situated on a hill at an altitude of 257 meters above sea level near the border with the Montiferru region. While its historical and cultural ties bind it to Planargia, its geomorphological structure links it to Montiferru. The territory features an irregular hilly profile and boasts a stunning coastline stretching from Foghe to Porto Alabe, characterized by wide beaches and vivid red sheer cliffs interspersed with the black sea stacks of Corona Niedda.

Etymology and Economy

• Etymology: The town’s distinctive name (Three Nuraghi) originates from the former presence of three ancient nuraghi within the settlement itself. Two of these have long since disappeared, while only a few courses of masonry remain of the third, Su Bastione, visible beneath a modern house.

• Economy: The primary sector centers on agriculture—cultivating cereals, wheat, vegetables, forage, olives, citrus fruits, grapes, and other produce—alongside livestock breeding. The town is also part of the production area for the renowned Malvasia di Bosa Doc white wine.

History

Inhabited since pre-Nuragic and Nuragic times, Tresnuraghes belonged in the Middle Ages to the Giudicato of Logudoro within the curatoria of Planargia. Over the centuries, it passed through various rulers, including the Malaspina family, the Giudicato of Arborea, and the Aragonese crown, subsequently becoming a fief granted to various noble houses (such as the Moncada, Villamarì, Brondo, and Olives families, and later the Paliaccio family under the Marquisate of Planargia) until the abolition of the feudal system in 1839.

Architecture and Landmarks

Its facade features six Ionic pilasters in trachyte and twin symmetrical bell towers with rococo cupolas, while the interior houses a single nave with barrel vaulting and decorative paintings by Isidoro Delogu.

• Church of San Lorenzo: A 17th-century church built in 1685 featuring a facade and jambs crafted from red trachyte.

Surrounding Archaeology and Coastline

• Nani Nuraghe and Apical Hole Light Phenomenon: A single-tower nuraghe surrounded by a double concentric wall and a village of circular huts. During the summer solstice, a narrow beam of sunlight penetrates through the apical hole of its intact tholos vault to illuminate the central chamber.

• Templar Church of Sant’Antonio da Padova: A probable Byzantine-origin rural church featuring robust buttresses and a red dome designed to recall regional shepherd dwellings (pinnettas).

• San Marco Campestre Church: Located on Su Monte e Santu Malcu, this church is the destination of a major annual procession on April 25 and the first Sunday of September, surrounded by traditional stone lodgings (domittas).

• Coastal Spanish Towers: The coastline is protected by several historic watchtowers, including Columbargia (the oldest, dating before 1572), Ischia Ruggia, and Foghe (built on a towering basalt cliff at the mouth of the Rio Mannu).

• Porto Alabe: The marine fraction of Tresnuraghes, featuring popular sandy beaches (Cala degli Albatros, Porto Alabe, and Sa Marinedda) backed by Mediterranean scrub.
