This 200-year-old signal tower houses a museum dedicated to the RMS Lusitania, which was torpedoed by a German U-boat in 1915 with the loss of 1200 lives. You can walk to the nearby clifftops for impressive views south towards the Old Head, the nearest point of land to the disaster; a privately owned golf club prevents you from reaching the lighthouse at the tip of the headland. The tower is 13km south of town via the R604.
