The current structure of the Ivrea Castle, located in the high section of the city, in proximity of the Duomo, is the result of subsequent transformations and reconstructions that however maintained the typical character of fortified architecture.
The first construction phase (1358-1394) involved the West end of the Castle, with the main or “maschio” tower, and the North tower, connected by a boundary wall, that was followed by the construction of two more towers towards the South and the East The subsequent construction phases built both new buildings and intervened on pre-existing structures. The Magno Palacio, still existing, preserves tiles with the Emblems of the Knights of the Order of Malta, leading to believe that in the current underground floor there was a community of the Gerosolomitano order, confirming the strategic role of the castle, even as part of the via Francigena route.
The most significant changes were recorded at the end of the 18th century, when the castle was transformed into a prison, first destined to State prisoners and then also to common prisoners. With the prison function, which it maintained untile the first half of the 20th century, the structure was subject to a series of additions and adaptations that naturally divided the courtyard into two parts and defined the external spaces, closed by high perimeter walls.
The first studies of the structure, including the historical origins, date back to the endo of the 19th century, important documental sources for this were contributed by Giuseppe Giacosa and Alfredo d’Andrade.
In 1979, almost ten years after dismission, the restorations were completed that demolished the structures from the 19th and 20th century and rediscovered the antique structures in the courtyard and moat areas.
Management of Castle tours is handled by the Volunteer Association “Castello d’Ivrea” that guarantees access during opening days.
