Spike Island Named Europe’s Leading Tourist Attraction by the World Travel Awards 2017!

Posted Posted in News

spike island

Spike Island has been named Europe’s Leading Tourist Attraction by the World Travel Awards 2017.  The island was originally a monastery before housing Fort Mitchel and its famous prison, the largest in Britain’s history. Although Spike Island has over 1,300 years of history, it has only been a tourist attraction for the last three years. This highlights Spike Island’s amazing accomplishment at winning Europe’s Leading Tourist Attraction, beating famous competitors like the Eiffel Tower, Buckingham Palace, and the Colosseum.

Callaghan Engineering were commissioned as the Mechanical and Electrical Design Team for this major tourism and heritage project initiated by Cork County Council. The project involved working closely with the Interpretive/Exhibition Design Team to realise this important historical site’s potential by renovating several buildings into a museum and interpretive centres with authentically retold guided tours, bathrooms, a cafe, and a gift shop.  We are proud to be a part of Spike Island’s ongoing history.

Spike Island – “Ireland’s Alcatraz”

Posted Posted in News

The recorded history of Spike Island begins in the 7th Century when it served as a Monastic site, but its chequered past has seen it serve as a Cromwellian deportation hub, a Royal Navy base, convict depot, naval garrison and later a prison, though much of its earlier narrative was also centred on detention and punishment.

Today’s visitor attractions on Spike Island tell its history through the newly constructed interpretive centre which was some 3 years in the planning eight months in construction.

The guided tour begins in the adjacent café which started out as a church and later served as a military drill hall. The tour covers each part of the new interpretive centre which itself consists of 4 distinct buildings, the Café, the Gaol, the Shell Store and the Gun Park.

Known as “Ireland’s Alcatraz”, Spike Island is now considered a go-to destination comparable with attractions such as the Guinness Storehouse and Bunratty Castle. It is anticipated that visitor numbers will exceed 100,000 per year by 2020.

Callaghan Engineering were responsible for the full M&E design which included converting the drill hall into a café and adding a new toilet block. The Spike Island complex has listed status and the design had to ensure limited visible effect on the buildings. Lighting was upgraded throughout, while an internal and external Wifi system was also installed.
