Belvelly (Irish: Béal an Bhealaigh, meaning "Mouth of the roadway")[1] is a small village on the northern end of the Great Island of Cork Harbour, about four miles north of the town of Cobh, County Cork, Ireland.
Belvelly is situated at the shortest crossing point between the Great Island and the neighbouring Fota Island, which is in turn connected to the mainland near Carrigtwohill.
The little village has two historic buildings, Belvelly Castle and the nearby Belvelly Martello Tower. The castle was built by the Hodnett family around the 15th century at a strategic location and much to the annoyance of the more powerful de Barry family, who later seized the castle.
