donore castle

In 1429 King Henry VI promised a grant of £10 to every one of his subjects who built a castle 20 feet long, 16 feet wide and 40 feet high before 1439 in Counties Dublin, Meath, Kildare and Louth. As this castle roughly conforms to these measurements, it is quite probable that it is one of these '£10 castles'.

There are 3 storeys, of which the ground floor is vaulted. The corners of the castle are rounded, and a projecting tower at the south-western corner contained the spiral staircase.
