Portencross
Portencross is a hamlet near Farland Head in North Ayrshire, Scotland. Situated about 3 km west of Seamill and about 2 km south of Hunterston B nuclear power station, it is noted for Portencross Castle.
It has two harbours and a pier. The "Old Harbour" is actually a small tidal inlet next to the castle, and is part of the castle property. The larger harbour, "North Harbour", owned by the Portencross Harbour Trust, lies about 100 m north of the castle and was the main access point for fishing activity.
The Portencross Pier was built in the era of Clyde steamer cruising but was never used as much as other locations such as Largs, Fairlie or Wemyss Bay
