The Montalbano Fortress, an updated report about a lost fortification in the Gulf of La Spezia

The following paper is an update for the research on the knowledge about the Montalbano Fortress, a crucial part of the Gulf of La Spezia's XIXth-century fortifications, comprising 42 structures and auxiliary settlements built to protect the maritime Arsenal. This study builds on a presentation at Fortmed 2024, offering expanded documentation of the fortress’s architecture. Part of a vast military system developed during the Napoleonic era, La Spezia's defences combined offensive and defensive roles. Declared a military port in 1808, the city was envisioned as an arsenal hub by architect Tagliafichi, though much of the plan remained unrealized. The fortifications included complexes defending both sea and mountains, with the Montalbano Fortress standing out as one of the largest and best-preserved structures. Recently, the Municipality of La Spezia began restoring abandoned fortifications, starting with the Valdilocchi Battery (2019–2022). The Montalbano Fortress is the next focus. This research uses a digital survey to reveal the fortress’s complex layout, hidden by overgrowth, and its well-preserved buildings. Highlighting its architectural and environmental significance, the study explores the potential for restoration and reuse as public space. It aims to promote an inclusive, sustainable process for regenerating the landscape and preserving this “lost” historical structure.
