Forte Belvedere, Military fort in Sampierdarena, Italy.

Forte Belvedere is a military fort in Sampierdarena with a pentagonal layout built on a hilltop position. Two bastions and defensive structures command the valleys of Certosa and Val Polcevera from this elevated location.

Work on the fort began in 1815, after the fall of Napoleon's empire and the annexation of Liguria by the Savoy states; a French spy reported work ending around 1825, but the house-fort still lacked vaults and terrace roofing, and the complex was finished around 1827. Its pentagonal plan was ringed by a ditch, with one bastion facing Certosa and another toward Sampierdarena. In 1889 the tower was demolished and ten underground casemates built.

The name Belvedere comes from the hill itself, fortified since the 14th-century Guelf and Ghibelline clashes. In the 1920s the rooms of the upper Belvedere Battery served as punishment cells, and prisoners' graffiti and drawings survive on the walls. Since the 1970s the Mauro Morgavi sports field has occupied the ground in front of the powder magazines.

The fort is accessible by hiking trails or vehicle, though visitors should expect uneven terrain and deteriorated structures. Careful navigation is needed as the site requires attention when moving around the complex.

In 1889 the fort was transformed into a coastal battery, requiring the original tower to be demolished. This radical redesign demonstrates how military technology and strategy evolved over the decades.
