Most traffic into Castlepark now arrives via the Duggan Bridge, built in 1976, which crosses the River Bandon from the northern, Kinsale, bank just east of the neck which joins the peninsula to the mainland.
[1] Among the old buildings on the peninsula are: James's Fort (early 17th century); Ringrone Castle (12th or 13th century), a former seat of the de Courcy Barons Kingsale;[2] and the ruins of Ringrone Church, the latter surrounded by an ancient graveyard that is still in use.
[3] Court records from the later seventeenth century show that much of the land was held by two families, the Brocketts and the Bathursts, both fairly recently arrived from England.
[citation needed] The rest of the peninsula consists of farmland with scattered housing.
Most of the land is used for tillage (cereals and sugar beet), although there is some grazing of cattle and sheep.
