Killiney Church is an ancient church in County Dublin, Ireland.
Killiney Church lies west of the coast, and south of Killiney Hill. In the modern day, this site is in the middle of housing developments, near Marino Avenue West.
A monastery stood on the site from the 6thâÂÂ7th century. The name of the 6th century site was Cill Ingean LéinÃÂn ("Church of the Daughters of LéinÃÂn"). These were seven virgin sisters, Aiglenn, Macha, Luiden, Druiden, Luicill, Bimtach, and Briga; the last is also patron of Tully Church. Their brother was Colmán of Cloyne (Colmán mac LénÃÂne; 530âÂÂ606). Their festival was celebrated on 6 March.
The church was built in the 11th century.
