Portora castle, strategically positioned by the narrow exit of the river Erne into the Lower Lough, was built for Sir William Cole who purchased the land in 1612.
In 1619 Pynnar described the castle as 'a bawn of lime and stone, 2.5m square, approximately 4m high, with four flankers and a stone house or castle three storeys high, strongly wrought'.Three of the flankers remain, the two on the west , flanking the walls of the castle. These round towers, about 3m in diameter, have several gun loops. Inside the castle can be seen proper fireplace chimneys in the N and W walls. The Cole family lived there prior to their move to Florence Court about 1764.
