Blackrock Castle was originally built on the Lee in 1582 by the citizens of Cork as a watch tower and fort to guard the river entrance against pirates and other invaders. In 1600 around tower was constructed by the Elizabethan government at the request of the citizens of Cork to protect them from marauding pirates and other invaders. Following a charter by James I in 1608, Blackrock Castle was handed over to the City of Cork.  In 1722 the old tower was destroyed by fire and was rebuilt with an octagonal room topped with a cupola.   The castle was used at this time as the Corporation banquet hall and for “throwing the dart”. 

For Cork Heritage Open Day 2013 the team at Blackrock Castle Observatory invited the people of the Rebel County to take a journey back in time with them to learn about the history of Blackrock Castle. A tour guide brought visitors to the lower turret overlooking Cork harbour and down to the dungeon, a National Monument, while they regaled you with tales of the past and present.

Booking is essential for this event and places are limited to 25 people on each of the four tours which are at 11:00 a.m., 11:30 a.m., 12:00 p.m. and 12:30 p.m.

 It was also possible to view the “If the Walls could Talk…”, DVD in Blackrock Castle Observatory, in the Make Space room, from 11am – 1pm while they are hosting the tours for Cork Heritage Open Day.  It was also on display as part of their regular tours in the afternoon too.
