Swords Castle was built as the manorial residence of the first Anglo-Norman Archbishop of Dublin, John Comyn, around 1200 or a little later in Swords, just north of Dublin. The castle was never strong in the military sense, but is unusual in that the perimeter wall of 305 metres is far larger than normal for an Irish castle. The walls enclose a large pentagonal walled area of nearly 6,000 m² (1.5 acres) with a tower on the north, probably the Constable's residence, and an impressive gateway complex on the south. Within the castle were the Archbishop's apartments, apartments for knights and a banqueting hall. The warder may have occupied the quarters to the left of the gate, while to the right was the janitor's room with the priest's room overhead. The adjoining chapel, built in the late 13th century, was probably used as the Archbishop's private oratory.
