Arthur Hussey, Notes on the churches in the counties of Kent… (1852)
“ Portslade.—A church of chancel, nave, south aisle and porch, and western tower. The chancel is E.E., containing a piscina, and three sedilia under trefoiled arches and a string-course. The nave with the piers and arches is Tr. Norm.; but the aisle, which once had an addition at the east end, appears to be E.E.; the porch is very plain, and later. The tower is E.E., except the upper part, which is Perp., to which style the font also belongs. The floor of the nave is an inclined plane, rising eastward, though almost imperceptibly. ”
