Archbold's Castle was formerly a fortified warehouse, of which two storeys remain. A
machicolation is visible above the doorway. Of seven castles which once stood in Dalkey, only two remain, Archbold's and
Goat Castle. Archbold is a
Hiberno-Norman surname, ultimately from
Norman Archambault (
ercan meaning "precious" +
bald meaning "bold"). ==References==
