Castle Dauphin is located in Pontgibaud, Auvergne, in central France, and was built to guard the bridge and principal route into southern France. Construction of the castle was begun at the end of the 12th Century by Robert I, Count Dauphin, of Auvergne.
The five story keep in the center of the walled courtyard is actually a double keep. There is limited access to the round tower, making it a place of final refuge in times of attack.
My reconstruction of Castle Dauphin is 30 x 30 inches (96 x 96 studs) and is about 29 inches high.
