The Balluderon Stone, otherwise known as Martin's Stone is a class II Pictish cross slab in situ at Balluderon, Angus.
A slab of Old Red Sandstone, the cross slab is situated in a field and protected by iron fencing. The slab, of which only the lower half remains, bears the remnants of a Celtic cross, two mounted riders, a serpent and z-rod symbol and a Pictish beast design. Local tradition associates the slab with the Legend of the Nine Maidens who were devoured by a dragon which was subsequently slain by a hero named Martin. Folk etymology names this as the origin of Strathmartine, the valley in which the slab stands.
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.
