Dalkey is a suburb of Dublin and seaside resort just south of Dublin City, Ireland. It was founded as a Viking settlement and became an important port during the Middle Ages. According to John Clyn, it was one of the ports through which the plague entered Ireland in the mid-14th century. In modern times, Dalkey has become a thriving seaside suburb and a minor tourist attraction. It has been home to many writers and celebrities including Jane Emily Herbert, Maeve Binchy, Hugh Leonard, Bono and Van Morrison.
