The Butler family handed Kilkenny Castle over to the people of Kilkenny in 1967 – for £50!
One of the most instantly recognised buildings in Ireland, Kilkenny Castle has been an important site since Strongbow constructed the first castle, probably a wooden structure, in the 12th century.
William the Earl Marshall (Strongbow's son-in-law) built the first stone castle on the site, which was completed in 1213. This was a square-shaped castle with towers at each corner; three of these original four towers survive to this day
The elevation of Kilkenny is 60 metres (200 ft) above sea level. The area of Kilkenny borough is 3.74 square kilometres (1.44 sq mi). Kilkenny is the smallest city in Ireland and although all cities in Ireland are by the coast or along a river Kilkenny is the only city that is not tidal.
Nowadays, Kilkenny Castle is effectively three-sided. One of the four walls - and one of the great round drum towers - has disappeared over time.
Where did it go? Well, the Eastern wall and the North-Eastern tower were blown up during the 1650 Cromwellian siege of Ireland.
Kilkenny is 117 kilometres (73 mi) away the capital Dublin and 48 kilometres (30 mi) north from the nearest city Waterford. Wexford is 80 kilometres (50 mi) to the south-east and Limerick is 122 kilometres (76 mi) to the west.
Kilkenny, an inland county, is bordered by counties Wexford, Carlow, Laois, Waterford, and Tipperary. Geologically speaking it is mostly limestone, with areas of black marble around Kilkenny city. The rivers Nore, Suir, and Barrow flow through it.
