What is "leopardstown"

Leopardstown is a district in Dún Laoghaire–Rathdown county, Ireland, located at the foot of the Dublin Mountains. A residential suburb in the east of the greater Dublin area, it is divided by the course of the M50 motorway, and adjoins the neighbouring areas of Sandyford, Stepaside, Ballyogan, Foxrock and Stillorgan. Leprosy was common in Dublin in medieval times and in the 14th Century a leper hospital was built near St Stephen's Green. It was later moved out to the Dublin mountains - the area where it was sited became known as Leopardstown.
