1861 Griffith's Map
Source: Griffith’s Valuation: Map of Knocknagoney. PRONI VAL/2A/3/4. 1861.
This diagram from the 1861 Griffith’s map shows the relationship between the Robert SLOAN's gate lodge and Clifton House, variously referred in the 1861 Griffith’s records as Clifton Manor, Clifton Ville and Clifden. It also shows the nearby roads, boundaries of the leases, the Tillysburn railway station and a causeway(?) extending into the Belfast Lough. Con Auld suggests that the structure over the mud flats of the Lough (a causeway?), could have been used to collect green seaweed for crop fertiliser (July 2008; pers. com.).
