While the entrance side of the building is done in a classical Palladian style with columns supporting a triangular pediment, the opposite side is Georgian Gothic with pointed windows, battlements and finials. …”

The perfect meeting spot to start any run in this area. From this point you can head either into Rostrevor village, out towards Killowen, into Kilbroney park or head north alongside the river.
