Castle of Caspian

The Castle of Caspian or House of Caspian was home to the early Telmarine Dynasty (the "Caspians") of the Kingdom of Narnia. The castle was home to various Telmarine kings of which included Caspian VI, Caspian VII and Caspian VIII, respectively. The first two names are speculation. The last permanent ruler of the palace by the name of "Caspian" was Caspian IX who was murdered and succeeded by his brother Miraz. Because Miraz became the final permanent ruler before it was abandoned or destroyed, the palace is sometimes called the Castle of Miraz. Afterwards, Caspian X may have lived in it briefly while king before rebuilding Cair Paravel and making it his new palace.

The castle itself may have been rebuilt from the remains of the White Witch's Castle and was located at Beaversdam, though on the opposite bank of the Great River.

Trivia
In Prince Caspian (Disney movie) the Castle was loctated on a large rock that might have been an Island.
