Agliè's main attraction is its Castello Ducale, one of the Residences of the Royal House of Savoy, listed in the UNESCO World Heritage Sites. Dating from the 12th century, it was originally a possession of the counts of San Martino. In the 17th century, it was turned into a rich residence by count Filippo d'Agliè, but was ravaged during the French invasion of 1706.
In 1765 it was acquired by Charles Emmanuel III of Savoy and sold to his son Benedetto of Savoy who had it radically renewed ten years later, under design by Ignazio Birago di Bòrgaro. Thenceforth it was a summer residence for the Kings of Sardinia. It was sold to the Italian state in 1939.
It has a monumental façade with two stairs and a fountain; the interior includes 300 rooms, mostly provided with contemporary furniture. The castle is surrounded by large English- and Italian-style gardens. It was used as the location for the Italian series Elisa di Rivombrosa as Rivombrosa.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
