The Château de Castelnau-de-Lévis was built at the beginning of the 13th century by Gicard Alamon, and called Castelnau de Bonnafonds. It was rebuilt by the Lévis in the 15th century, when the seigneurie came into the possession of Hugues d' Amboise, baron d'Aubijoux; the fief remained with his descendants until the seventeenth century. Hugues' grandson, Louis d'Amboise, comte d'Aubijoux and baron de Castelnau-de Bonnafous, restored the castle and dwelt in it. The narrow square watchtower (tour de guet) is 40m tall.
Apart from the watchtower, all that remains today are remnants of other buildings. From the castle, there is a good view of Albi and the Tarn valley.
The castle is privately owned.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
