Carrickabraghy Castle (Caisleán Charraig Bhrachaí) on a rocky outcrop at the north-western extremity of the Isle of Doagh in the north of Inishowen, a peninsula on the north coast of County Donegal, Ireland.
From the 9th to the 13th century Inishowen was politically divided into three 'tuatha' or districts. These were known as Aileach in the south, Bredach to the east and Carraig Bhrachai to the west. The Lords of Carraig Bhrachai ruled from the town-land of Carrickabraghy, the area where the Castle now stands. They were one of the most important families in Inishowen.
Carraig Bhrachai is not mentioned again in the history books until 1600. The present remains of the castle are thought to have been built around this time. The O Dochartaigh Clan had risen into power in Inishowen and the Chief of the clan and Lord of Inishowen was Sean Og O Dochartaigh. The English invasion of Ireland was well underway, and to protect his livestock and supplies from English raids, Sean Og decided the best place to store them was on The Isle of Doagh.
Around 1665 Carrickabraghy Castle was abandoned, and began to decline for several centuries.
Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
