History
Forte San Pietro is a Medici-period defensive fortification in Livorno, Italy, built to protect the adjacent Venezia Nuova district. Construction began on 14 July 1682, when Governor Marco Alessandro del Borro initiated the project on the birthday of Grand Duke Cosimo III. The work was completed in approximately six years and became part of Livorno’s northern defensive system.
The Medici defensive system
The fort extended northward from Venezia Nuova and joined Fortezza Nuova, a historic fortress that formed part of Livorno’s northern defenses. The arrangement completed the symmetry of this defensive sector. The Canale dei Navicelli was diverted beside Forte San Pietro before returning to its original course, allowing the defensive complex to be bypassed.
In the late 1780s, the Rivellino di San Marco was founded between Fortezza Nuova and Forte San Pietro and completed during the following decade. A rivellino, or ravelin, is a detached defensive work placed in front of a fortress to protect an entrance or strengthen an approach. Its construction made the two forts symmetrical elements around the outwork, while the Porta San Marco provided access to the city near the church of Santa Caterina.
Military service and later uses
Forte San Pietro took part in the defense of Livorno during the Austrian invasion of 1849. Its military function ended during the nineteenth century. The site was first used as a timber depot and later housed Livorno’s public slaughterhouses, which were transferred into the fort’s perimeter from another location.
Construction of Livorno’s customs boundary began beside Forte San Pietro in 1834, where the boundary met the ditch protecting the fort. Part of the ditch was redirected toward the large Dogana d’acqua dock along the Canale dei Navicelli. The relocation of the Porta San Marco later placed it near the site where Livorno’s first railway station was subsequently built.
Twentieth-century alterations
During the twentieth century, Forte San Pietro and the Rivellino di San Marco underwent substantial alterations. The external ditch between the former military structures was progressively and partly filled, and part of the fort’s walls was demolished. These changes substantially altered the original defensive layout. Proposals to restore the buried water area, relocate the adjacent sewage-treatment plant, and fully enhance the fort were not implemented because moving the plant would have been costly. Renewal of the existing installations was instead considered. Forte San Pietro is identified as a military architectural monument of Livorno.
Remains
Forte San Pietro survives as a large defensive work extending northward from Venezia Nuova toward Fortezza Nuova. Its original setting combined earthworks, masonry walls, water-filled defensive spaces, and associated artillery positions. Later filling of the external ditch and demolition of part of the walls have changed the fortifications around it, so the surrounding area no longer preserves the original defensive configuration.
Forte San Pietro
The fort’s earthwork included several pits used to store grain during its military period. A ditch protected the fort, with part of its course later directed toward the Dogana d’acqua dock along the Canale dei Navicelli. The external ditch between Forte San Pietro and the Rivellino di San Marco was subsequently partly buried. These alterations affected the water defenses and the physical relationship between the fort and its detached outwork.
Rivellino di San Marco
The Rivellino di San Marco occupied the position between Fortezza Nuova and Forte San Pietro and was separated from the surrounding fortifications by water. Before its early-nineteenth-century redevelopment, it had a broadly triangular open plan. Its two sides adjoining the forts contained earthworks and batteries facing the ditch, while its pointed outer end had defensive walls and four gun embrasures on each side. A gun embrasure is an opening through which artillery could be fired. Small sentry boxes stood at the corners.
Access to the rivellino was provided through the Porta San Marco after a crossing over the ditch. On the opposite side, the Porta Rivellina connected with the far bank by a wooden bridge. A small arms square on the ramparts linked with the road to Torretta. The customs boundary later abutted Forte San Pietro, while the relocation of Porta San Marco brought that entrance close to the later site of Livorno’s first railway station.
