Place & story

A royal settlement under pressure

Medieval Newcastle was a royal manor positioned to protect the coastal route between Bray and Arklow. Its castle existed by about 1210 and became a base for campaigns into the Wicklow uplands. Documents from 1304–05 record 191 burgages and two mills, evidence of a substantial organised settlement. Its history was also one of repeated destruction. The archaeological survey records burnings in 1295, 1315, 1370, 1376 and 1405. After the last of these, Newcastle passed into O'Byrne control and the borough disappears from the surviving documentary record. [2]

The marsh and the market garden landscape

Lewis's 1837 description distinguished Newcastle's lower village from the higher settlement around the church, with views across farmland to the sea. Agriculture supplied the Dublin market with early lamb and veal, and a long white potato called Bangor was widely grown. Along the coast, artificial drainage trenches protected cultivated ground from flooding. Peat from beside the Cooldross marsh was used for fuel, while further turf came from the mountains. His account places the village within a working coastal landscape of drainage, cultivation and connections to the capital. [3]

The church built in stages

The Church of Ireland parish church was built between 1783 and 1788. Its three-stage tower followed in 1821 and the chancel in 1856, creating a building whose present outline reflects several generations of work. Rubble walls are finished with granite corner stones and dressings. The tower carries a clock, battlements and tall pinnacles, while pointed windows light the nave and transepts. The associated sexton's house and churchyard complete the group. Its elevated setting gives the late Georgian church a strong presence beside the remains of the medieval manor. [4]
