Aghalurcher (meaning 'Field of the Cast') was a pre-Norman monastery located east of the shore of upper Lough Erne, Northern Ireland, founded according to legend by Saint Ronan in the sixth to early seventh century and dedicated to him in the ninth century. The site includes the ruins of a medieval church with a small gated vault (locked) (where sculptural fragments are stored) and a gateway constructed with stones from the church. The church was remodelled in 1447 with a new roof added. The site seems to have been abandoned after a murder on the altar effectively deconsecrated the church.
The site includes some interesting gravestones of the late eighteenth century, plus an early medieval carved head on the gateway. Additional sculptural fragments from the site are at the Fermanagh County Museum at Enniskillen Castle.
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.
