As soon as daylight broke we went on shore, and walked to the old castle of Inverlochy.  It stands above the river, and consists of four large round towers connected by high walls, forming an extensive quadrangle. The greater part is entire; indeed, the walls being ten feet thick are calculated to stand for ages.  A moat surrounds the walls.  The principal entrance is on the south-east side, and directly opposite it is a sally-port.  Above the gateway was a guard-room, defended by iron gates and a heavy portcullis.
