Doe Castle was the historical stronghold of Clan tSuibhne (Clan McSweeney), with architectural parallels to the Scottish tower house. Built in the early 15th century, it is one of the better fortalices in the north-west of Ireland. The castle sits on a small peninsula, surrounded on three sides by water, with a moat cut into the rock of the landward side. The structure consists mainly of high outer walls around an interior bawn with a four-storey tower-house or keep.
Doe Castle was most likely built c.1420 by the Quinn family, but by the 1440s, it had come into the hands of the gallowglass MacSweeney family. The castle remained in the hands of a branch of the Clan Sweeney known as Mac Suibhne na d'Tuath (Mac Sweeney Doe) for almost two hundred years until it was seized by King James VI and I because the MacSweeneys had rebelled against him. On 7 March 1613 during the Plantation of Ulster, the king granted the castle, along with other lands, to the Attorney-General for Ireland, Sir John Davies (poet, born 1569). On 31 December 1614, Sir John sold the castle to an English settler, Captain John Sandford from Shropshire, England.
The castle changed hands repeatedly during the 17th-century struggle for control of Ireland between the English and the Irish. It is known that in 1650, Sir Charles Coote, the Governor of Londonderry, took possession of the castle. Eventually, the castle was bought by Sir George Vaughan Hart and inhabited by his family until 1843.
In 1932, the castle came into the hands of the Land Commission, and in 1934 was declared a national monument and was acquired by the Office of Public Works. The tower house element of the castle underwent a major restoration in the 1990s.
The castle grounds are open daily and guided tours of the tower house are available during the summer months.
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.
