Carrigadrohid castle stands on a rock in the middle of the river Lee, adjacent to the bridge which gives the village its name. It was erected in 1455 by the MacCarthys of Muskerry, with an extension to the east and an annex to the north being added in subsequent centuries. In 1650, it was besieged by Parliamentary forces following the Battle of Macroom, and
Boetius MacEgan, the
Bishop of Ross, was hanged by the reins of his own horse outside the castle having refused to implore the Irish garrison to surrender to the Cromwellian army. The MacCarthys were dispossessed, and the castle ended up in the hands of the Bowen family. It was last inhabited in 1750, and in 1770 it was recorded as falling into the state of disrepair. In the 20th century further erosion and acts of vandalism contributed to progressing deterioration of the ruins. In 1950, on the 300th anniversary of Bishop Boetius's death, a local effort was made to have the castle preserved, but it was unsuccessful. with the aim of preserving the castle. In 2006, the Office of Public Works was tasked with starting the initial phase of conservation and safety work where the castle meets the public road, with the budget of 100,000 euro. It was also estimated that the full conservation project would cost up to 1 million euro, and that it was beyond the scope of the city council. The positioning of the castle on the river is what makes it unique among Irish castles. The annex included a staircase. ==Sport==
