Ivrea Castle was built on behalf of Amadeus VI, Count of Savoy, in 1358. Ivrea was built to signify the dominance of the House of Savoy over the region. The castle has four towers erected on a plan flank. It is located next to a cathedral and a bishop's palace. The castle is mentioned in the work of Giosuè Carducci.
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.
References:The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
