Torre di Barì, Spanish watchtower in Bari Sardo, Italy.

Torre di Barì is a truncated-cone tower of local granite and basalt on a small promontory on Sardinia's eastern coast. It stands 12.75 m high, with a base diameter of about 11 m narrowing to 8 m at the terrace. Its entrance, about 4 m above ground, opens into a circular room of roughly 14 m² with a domed ceiling.

Marco Antonio Camos, captain of Iglesias, recommended building the tower in 1572 to counter pirate raids and to control the mouth of the rio Mannu, a freshwater source sought by corsairs. Construction likely began after 1572 and was officially attested around 1639. The 250-scudi cost fell on the population of Bari Sardo, which also had to feed the alcalde and three or four soldiers.

The beach either side of the promontory carries separate Sardinian names: "de is ominis" (of the men) on the left, with sand coarse as rice grains, and "de is feminas" (of the women) on the right, made of larger pebbles. The split comes from an old rule that men and women could not bathe in the same place.

The tower stands on a small promontory reached from the beach; a staircase built around the early 1900s, replaced in the second half of the 1990s with one fitted with parapets, leads to the hatch about 4 m above ground. Visits are mostly possible in the summer months. The beach left of the promontory has coarse sand, the right one pebbles.

The tower's garrison had three cannons, two swivel guns and two rifles, and the upper terrace served as the piazza d'armi where this ammunition was kept. Look for the niches fitted with window frames during the 1990s restoration; they once served both for lookout duty and as gun ports.
