Porte du Scex Castle was originally built to protect the territory of Vouvre and collect tolls. In the Middle Ages it was owned by Savoy and Tavelli de la Tour families. The castle was rebuilt between 1591 and 1609 and again in 1678. The museum opened in the Porte-du-Scex castle in 2008. It houses an interactive and in 3D model of the Chablais region, that is part of the permanent collection. Other rooms are dedicated to temporary exhibitions concerning the history and cultural heritage of the region, and which change every two years.
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.
