Donegal Abbey is a ruined Franciscan Priory in Donegal in Ireland. It was constructed by the O'Donnell dynasty in the fifteenth century. It is sometimes referred to as Donegal Friary.
It was built in 1474 on the orders of the leading Gaelic lord of the area, the ruler of Tyrconnell Hugh Roe O'Donnell, the First, and his wife Finola O'Brien.
In the Nine Years' War, the Abbey was used for a meeting between the rebel leadership and envoys of the Spanish King Philip II. The Abbey was the scene of fighting during the 1601 Siege of Donegal when a force led by Red Hugh O'Donnell attempted to capture the town from Crown forces led by the Gaelic warrior Niall Garve O'Donnell.
During the battle, on 10 August 1601, a fire broke out at the abbey which in turn ignited a store of gunpowder kept by Niall Garve. The resulting explosion destroyed most of the building and killed hundreds of Niall Garve's soldiers, including his brother Conn Oge O'Donnell.
The abbey was not rebuilt, and remains in ruins, but the Franciscan friars set up a new base at a refuge close to the River Drowes, near Ballyshannon.
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.
