Castlefinn (site of) (DG079-023001-): This O'Donnell castle undoubtedly served to guard a ford on the River Finn. Nial Garbh O'Donnell resided here in 1601 (CSPI 1600-1, 278). In 1622, it was described as 're-edified with good additions to it by Sir John Kingsmill' and had a strong bawn (DG079-023002-) adjoining it (Treadwell 1953-5, 516). It had fallen to ruins by 1654-6 (Simmington 1937, 23). In 1618/19 Nicholas Pynnar described the home of Sir John Kingsmill as 'a Bawne of Lime and Stone 100 feet [30.4m] square, with two Flankers, the which are two stories high, with good Lodgings in them, and a very strong stone House three stories high; himself with his Wife and Family dwelling therein. Near to the Bawne is built a Village' (Hill 1877, 518). According to local tradition this 17th century bawn known locally as Kingsmill Bawn was not built on the site of the medieval O'Donnell castle (DG079-023001-) but was located in the centre of the 17th century village of Castlefinn. The modern R.C church dedicated to St. Mary now occupies the site of the 17th century bawn. Kingsmill's bawn was built on the site of the old Manor house where Captain Butler once lived and is now where the New Roman Catholic Church St. Mary's stands. This site was previously owned by Captain Butler and his family home was demolished in the mid 1960's (Knox 2003, 31).

Built by the O'Donnell clan, Castlefinn was held by Nial Garbh O'Donnell in 1601 and served as a strategic stronghold to control a ford on the River Finn. It is remembered for its role in the regional power dynamics of early 17th-century Ulster.
