The Borgo Medioevale in Turin, Italy, is an open air museum and reconstructed medieval village and castle. It is located in the Parco del Valentino (Valentino Park) on the riverbank of the Po river. It was built for the 1884 Italian general exposition and it was constructed by replicating and mimicking late-medieval architecture of the Piedmont region.
The reconstructed architecture, decorations, and landscaping followed strict criteria of faithfulness to historical models. Over 40 sites (including castles, villages, and churches) all across Piedmont and Aosta Valley were used as models and many intellectuals, historians, artists and technicians took part in the project. Among the structures that served as models are Fénis Castle, Issogne Castle, Verrès Castle, and Ivrea Castle.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
