Killiney Hill is the southernmost of the two hills which form the southern boundary of Dublin Bay, the other being Dalkey Hill. These two hills form part of Killiney Hill Park.

Dalkey is an affluent suburb of Dublin, and a seaside resort southeast of the city, and the town of Dún Laoghaire, in the county of Dún Laoghaire–Rathdown in the traditional County Dublin, Ireland. It was founded as a Viking settlement and became an active port during the Middle Ages. According to chronicler John Clyn (c.1286–c.1349), it was one of the ports through which the plague entered Ireland in the mid-14th century. In modern times, Dalkey has become a seaside suburb that attracts some tourist visitors.
