Llanthony Priory s a partly ruined former Augustinian priory. The priory dates back to around the year 1100, when Norman nobleman Walter de Lacy reputedly came upon a ruined chapel of St. David in this location, and was inspired to devote himself to solitary prayer and study. A church was built on the site, dedicated to St John the Baptist, and consecrated in 1108. By 1118, a group of around 40 monks from England founded there a priory of Canons Regular, the first in Wales.
In 1135, after persistent attacks from the local Welsh population, the monks retreated to Gloucester where they founded a secondary cell, Llanthony Secunda. However, around 1186 another member of the de Lacy family, Hugh, the fifth baron, endowed the estate with funds from his Irish estates to rebuild the priory church, and this work was completed by 1217.
The Priory became one of the great medieval buildings in Wales, in a mixture of Norman and Gothic architectural styles. Renewed building took place around 1325, with a new gatehouse.
Following Owain Glyndŵr's rebellion in the early 15th century, the Priory seems to have been barely functioning. In 1481 it was formally merged with its daughter cell in Gloucester, and after 1538 both houses were suppressed by Henry VIII's Dissolution of the Monasteries.
The buildings at Llanthony gradually decayed after the Dissolution to a ruin, although in the early 18th century the medieval infirmary was converted to the Church of St David. In 1799 the estate was bought by Colonel Sir Mark Wood, the owner of Piercefield House near Chepstow, who converted some of the buildings into a domestic house and shooting box.
The ruins have attracted artists over the years, including J. M. W. Turner who painted them from the opposite hillside. Wood's house later became the Abbey Hotel. The remaining ruins are protected by Cadw and entrance to the ruins is free.
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.
