The Château d'Esparron-de-Verdon is located in the commune of Esparron-de-Verdon in the Alpes-de-Haute-Provence department.
The first mention of a castle in Esparron dates back to 990. A charter from the abbey of Lérins, dated that year, refers to a church dedication near 'castrum Sparronis, in Bulzolschi valle.' Historian Mathieu Vivas suggests this text dates more likely to the 1020s, tied to the incastellamento phenomenon in Provence, during which fortified settlements emerged. In 1182, a man named Bertrand d'Esparron is cited in the cartulary of the Saint-Victor Abbey in Marseille.
Agnès Spata, daughter of Augier Spata, married Boniface IV de Castellane in the early 13th century. The Castellane family, one of the oldest Provençal families, shared lordship of Esparron with the d'Esparron family during the 13th and 14th centuries. By the 15th century, the Castellane family became sole lords of Esparron through marriage and purchase.
A square tower, 9 meters wide with walls 1.5 meters thick, was constructed in the early 13th century. Modifications occurred between 1520 and 1540, with additions like a latrine tower and a spiral staircase.
In the late 18th century, the east wing was restored with modern touches like adjoining rooms, salons, and ceremonial chambers. The current owner, Count Bernard de Castellane-Esparron, inherited the estate in 1989 and, along with his wife Charlotte-Anne, has since converted the castle into a guesthouse.
The castle features a 13th-century square keep, modified in the 15th century, as well as remnants of curtain walls and living quarters from the 15th and 17th centuries. In the latter half of the 18th century, the seigneurial castle was transformed into a pleasure residence by reconstructing the south wing.
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.
