Portencross Castle stands on a rocky outcropping overlooking the Firth of Clyde on the west coast of Scotland. The site, with a small harbor, has been fortified since the 11th Century. The estate was given to Robert Boyd by King Robert the Bruce in 1314. The current castle was started by his grandson.
The castle began as two story hall house. Later, an upper floor and a tower with a spiral staircase were added. The door on the ground floor leads to store rooms. The main entrance to the castle is on the floor above.
My reconstruction of Portencross Castle is 25 inches long, 15 inches wide (80 x 48 studs) and is about 22 inches high.
