Dornoch Cathedral was built in the 13th century, in the reign of King Alexander II (1214–49) and the episcopate of Gilbert de Moravia (later Saint Gilbert of Dornoch) as the cathedral church of the diocese of Caithness.
In 1570 the Cathedral was burnt down during local feuding. Full restoration was not carried out until the early 19th century, by the Countess of Sutherland. Among the 'improvements' carried out, the ruined but still largely intact aisled medieval nave was demolished and a new narrow nave without pillars built on its site. The interior was reordered in the 1920s by Rev. Charles Donald Bentinck, with the removal of Victorian plasterwork to reveal the stonework (although the medieval church would have been plastered throughout). The site of the medieval high altar was raised and converted into a burial area for the Sutherland family, who introduced large marble memorials alien to the original appearance of the building.
The Cathedral's churchyard is adjoined by Dornoch Castle, the somewhat reconstructed remains of the medieval palace of the Bishops of Caithness.
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.
