A history of Blackrock Castle
The history of Blackrock Castle is long and colourful, and I’m not going to be able to do it justice with a handful of paragraphs.
The below is intended to give you an overview of the history of Blackrock Castle – you’ll discover the rest when you walk through its doors.
The early days
Blackrock Castle began life as a coastal defence fortification in the 16th century. It was built to protect Cork Harbour and port from pirates and potential invaders.
The citizens of Cork asked Queen Elizabeth I for permission to build the fort, and the early building was constructed in 1582, a round tower added in 1600 to stop pirates pouncing on any vessels entering the harbour.
The castle was in the ownership of the city after King James I granted a charter in 1608 and there are references to it in the Council Book of Cork in 1613 and 1614.
Fires, banquets and tradition
like many old buildings, the castle suffered its fair share of destruction over the years. Fire hit in 1722, wrecking the old tower, which was rebuilt by the city’s citizens soon afterwards.
Descriptions of the castle during this period show that it was used for banquets and social gatherings, including one referred to as ‘throwing the dart’.
This tradition that is thought to date back to at least the 18th century involved the city’s mayor throwing a dart from the boat and was held every three years. This was a symbolic demonstration of the Cork Corporation’s jurisdiction over the harbour.
After a banquet in 1827, fire once more destroyed the castle. Mayor Thomas Dunscombe ordered its rebuilding in 1828, completion achieved by March 1829.
The architects added another three stories to the tower and rebuilt the out buildings. The castle entered private hands and was used in the 20th century as a private residence, offices and a restaurant.
The Cork Observatory
The Cork Corporation reacquired the castle in 2001. Work began to repurpose the building as an observatory and a museum – as it is today. The castle houses a
working professional astronomical observatory, which is staffed by researchers from CIT searching for new planets around distant stars. There are many public exhibitions on the scientific themes of the observatory and educational events and tours for school pupils and students.
