The extant 13th-century structure consist of a ground-floor undercroft, which has a rock face forming its eastern wall due to its elevation.

[3] Two staircases remain on the eastern wall, cut into the rock and leading to the lobby area of the hall.

There is a two-storey chamber section on the north side of the tower, which has a polygonal stair turret to its northwest corner.

[3] The Percy estates, including Spofforth, were confiscated after the rebellion against King Henry IV in 1408 and given to Sir Thomas Rokeby.

They were later restored and then lost again in 1461 when the Percys supported the losing side in the War of the Roses.
