Castle Donovan
Castle Donovan is the remains of a 16th-century Irish tower house that served as the seat of the Clann Cathail branch of the O'Donovans. Built on a rock beside the River Ilen, much of the tower was later destroyed (traditionally in the 1640s), and today over two thirds remain as a conserved national monument.

As it stood in 1580
The shape it held in its prime.
A rectangular stone tower house rising roughly four storeys (about 60 feet) with a castellated parapet and a projecting spiral-stair turret, set directly on a large rock outcrop at the bank of the River Ilen. In its prime the tower stands complete with its west and south walls, an enclosing bawn and attached outbuildings, and a continuous masonry roofline with crenellations; it occupies a marshy meadow in a narrow valley ringed by low, rocky, heathy hills.
Its story
The story of Castle Donovan.
Castle Donovan, in a valley near Drimoleague, was the so-called "seat" of the Clann Cathail sept of the O'Donovans for a period during the 16th century. The tower house, approximately 60 feet high, sits on a large rock outcropping — which forms its ground floor — close to the bank of the River Ilen. Before the 17th century it was called Sowagh; the name Castle Donovan, after the Manor of the Castle of O'Donovan, is associated with a regrant of 1615.
It is commonly believed to have been built, or at the very least augmented, by Donal of the Hides, Lord of Clancahill from about 1560 to his death in 1584. His son Donal II O'Donovan repaired or altered the structure some decades later but was not living in it by then — the family had already relocated to the more profitable Rahine Manor on the seacoast to protect their maritime interests.
According to tradition the tower was severely damaged by Oliver Cromwell's soldiers in the late 1640s, blown up with powder in retaliation for Donal III O'Donovan joining the Stuart side and for his involvement in the rebellion of 1641; it has been uninhabited since. The bawn and outbuildings are gone and the western wall later collapsed, but over two thirds of the tower still stand, conserved by the Office of Public Works between 2001 and 2014 as a listed National Monument.
