Hodnett tower house, 14th-15th century
Belvelly Castle
Belvelly Castle is a four-storey tower house built by the Anglo-Norman Hodnett family, who came from Shropshire to this corner of Cork Harbour in the 12th century. It guarded the ford linking Great Island to the mainland. The de la Roche and de Barry families took it in the 14th century; Walter Raleigh is loosely tied to it in the 16th, and Roger Boyle, first Earl of Orrery, garrisoned troops in it during the Irish Confederate Wars of the 1640s. By the 19th century it was a ruin. Sold in the early 2000s and granted planning permission in 2016, it was rebuilt over three years in a restoration that ran to several million euro - additional stone hauled from an old mill at Cloyne in East Cork. It is now a private home, not open to the public, but it is unmistakable from the bridge road, with a bronze figure and a gold-leaf tree sculpture set on the roof.
Napoleonic gun tower, 1813-1815
The Belvelly Martello Tower
Just beside the castle stands a Martello tower, one of a ring of them thrown up around Cork Harbour during the Napoleonic Wars. The site was chosen in 1811 by a Royal Engineers officer and the tower built between 1813 and 1815, with walls reported at thirteen feet thick. It was never meant to fight warships - it sat to cover the shallow, tide-bound channel behind Great Island, the fear being that French longboats of marines might slip up the back way toward Cork city, seven miles upriver. Troops were stationed here during the First World War. In 1922, during the Civil War, the IRA blew out the tower's interior to deny it to the National Army. It sat gutted until 2006, when the inside was completely rebuilt as a luxury private home.
Belvelly Bridge, 1803
The bridge and the one way in
Belvelly Bridge, built in 1803, carries the R624 across the north channel and is the only road onto Great Island. That single fact explains the whole place: two families and two empires fortified this crossing because whoever held it held the door to the island and, behind it, the approaches to Cork Harbour. The bridge is now more than two hundred years old and groans under modern Cobh commuter traffic; the county council has talked for years about upgrading it. At the Cobh end of nearby Fota station runs the Belvelly viaduct, carrying the railway across the same waters.
