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 Bridge (built in 1803)[2] connects Great Island to Fota Island, which is in turn connected to the mainland near Carrigtwohill.

The village has a number of historic buildings; Belvelly Castle, Belvelly Martello Tower[3] and a nineteenth century red-brick school house.

[5] Because of the 13-foot-thick (4.0 m) walls and its status as a historical monument, limited structural changes could be made to the Martello tower, with most light coming from the roof area.

The restoration of Belvelly castle included the construction of new perimeter walls and a separate garage.
