Portaferry Castle is a small tower house in built in the 16th century by William Le Savage. In 1635, Patrick Savage's brother-in-law, Sir James Montgomery of Rosemount (Greyabbey), repaired the castle by roofing and flooring it so that his sister could live in greater comfort there.
It is a square building with a small projecting turret on the south corner. It is three storeys high plus attic and there is no vault. Most of the eastern corner is in ruins. The entrance at the base of the tower is protected by a small machicolation and the entrance to the ground floor chamber is protected by a murder-hole. A curved stairway within the tower rises to the first floor and a spiral stairway in the west corner continues to roof level.References:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
