Garbally Castle was built in 1499 by
Malachy O'Kelly as a tower house, the Kelly clan being renowned in Ireland at this time as builders of fortresses. The castle was destroyed by
MacWilliam De Burgo in 1504, he also destroyed two other O'Kelly fortresses at this time at
Monivea and
Gallagh. However, the extent of the destruction inflicted is uncertain as in 1832
Samuel Lewis noted that Garbally castle was "partially destroyed by
Cromwell" along with the nearby castle in the 17th century. After this time the lands were owned by three
Roman Catholic landowners, two of the named Patrick Ffrench, but by the
Griffiths Valuation of Tenements in the early 1850s, Robert French, a diplomat who served as Secretary to the British Embassy in
St. Petersburg and
Vienna was the owner of the entire townland. Garbally was at this time leased to the Blake family and occupied by one Thomas Blake who was the son of the M.P., Patrick Blake. Patrick Blake was a participant in the trial of
Neddy Lohan. ==The ruins==
