CIT Blackrock Castle Observatory

CIT Blackrock Castle Observatory (CITBCO) is a 16th century Castle located 4km from the heart of Cork city on the banks of the river Lee. It was built by the citizens of Cork in 1582 as a watch tower and fort to guard the river entrance against pirates and other invaders. The tower also acted as a sentinel to guide shipping safely to and from the port. Indeed the motto on the crest of Cork City above the Latin phrase: “Statio Bene Fida Carinis” means “a safe harbour for ships”.

While a few remains of the original building still stand, most of it was destroyed in a fire in 1827 and replaced with the current structure that was completed in 1829. While the castle was used for a variety of purposes throughout the ages, it now serves as Ireland’s first fully interactive astronomy centre, which is open to the public.

Behind the scenes guided tours will bring the past present and future together and take you down to the Dungeon, a National Monument out on to the turret where you can take in views of Cork Harbour. These tours are at specific times only so please call ahead to confirm.

The Observatory

At Blackrock Castle you will find a working professional astronomical observatory, staffed by researchers from CIT engaged in searching for new planets around distant stars using telescopes at CITBCO and abroad. The integration of the public exhibition and the astronomical observatory makes BCO a unique national research and education centre.
