The "caput", or family seat, has been in several locations over the centuries, usually in the east of Ulster. Joymount House was built for The 1st Baron Chichester in the 1610s in Carrickfergus in the south-east of County Antrim, probably being completed in 1618. Joymount, along with Chichester House on the outskirts of Dublin and the Plantation-era Belfast Castle in Belfast, were the three original principal residences of the Chichester family in Ireland. Lord Chichester maintained Chichester House, located on the Hoggen Green (now College Green), as his 'town' residence on what was then the eastern edge of Dublin. Joymount House was probably demolished in the early eighteenth-century, while Parliament House was built on the site of Chichester House in Dublin in the early 1730s. The Plantation-era Belfast Castle was largely destroyed by fire on 24 April 1708 and was not rebuilt.
