The Post Medieval Period commences with the Irish Wars and then Plantation (1605-1690). New settlements sprung up as land previously held by native and Anglo-Norman or Anglo-Irish families was confiscated and given over to Loyal British Protestant subjects, mainly Scots and English. During this period most of the tower houses appear and develop, new towns are formed and many fortified sites such as star-shaped forts appear in the landscape. Around the shores of Lough Neagh there four tower houses dating to this period which are still standing and these are; O’Connor Stronghold on Derrywarragh Island; Shane’s Castle; Mountjoy Fort at Magherlamfield; and Salterstown Castle.

From the early 18th century Irish landed estates grew and developed, with many early mansion houses created as their centrepiece. These sites are also an important source of evidence for farming, woodland management and industry. For Lough Neagh demesnes were located at Antrim Castle, Langford Lodge, Shane’s Castle and also Portmore Castle. During restoration works at Antrim Castle Gardens excavations to identify the original garden layout were carried out by Terence Reeves-Smyth and Malachy Conway in 1991 and 1994.
