Mornas Fortress was already mentioned in the 9th century under the name of Rupea Morenata, the fortress, probably built in wood, was there to protect the village of Mornas. Built on a rocky outcrop, it offers incomparable views over the Rhône River. It was rebuilt of stone from the 12th century onwards.
Propriety of the Counts of Toulouse then the Papacy, Catholics and Protestants fought fiercely over it during the wars of religion. In 1562, after massacring the women, children and elderly in the chapel, the Protestants troops under the command of the cruel Baron des Adrets forced the Catholic garrison to throw themselves off the walls. This sadly notorious episode is called Sauto Barri ('wall jump'). The Huguenots met the same fate when the fortress was recaptured by the Catholics in 1568. After the French Revolution, the fortress was abandoned and fell to ruin.
Since 1978, the dynamic association Les Amis de la Forteresse has been restoring it and has brought it back to life as in medieval times, organizing fun pageant tours with the visitor being welcomed by knights and lords in period costume, for the pleasure of all, especially the children.
For those who want to continue their excursion, a cliff path winds along to the small Saint-Baudile Chapel.
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.
