The Casino was designed by Sir William Chambers as a pleasure house for James Caulfeild, 1st Earl of Charlemont. It is one of the finest 18th century neo-classical buildings in Europe The Casino, meaning “small house”, surprisingly contains 16 finely decorated rooms, endlessly rich in subtlety and design. It is a remarkable building – both in terms of structure and history.
Seen from the outside, the building has the appearance of a single roomed structure, with a large panelled door on the north elevation and a single large window on each of the other elevations. This is all illusion, however, as it actually contains 16 rooms on three floors.
The underground tunnel at the Casino was used as a shooting range by Irish revolutionaries including Michael Collins in the 1920s
The Casino is located at Marino, just off the Malahide Road and only three miles north of the centre of Dublin.
