The First Floor of the Inner Ward provided living quarters for several Triskelion family members and some of their most valued servants. The majority of the rooms are of dressed stone, with wooden beams supporting the ceilings. Ceiling height is generally sixteen feet. Interior light was generally provided by candles and there are mounted candle-holders on most of the walls in the corridors.
The north-facing portion of the Inner Ward on the Ground Floor was without windows due to the presence of solid rock where the castle was dug out of the mountain. The first and higher floors, however, are above the foot of the mountain and have north-facing windows.
The First Floor directly connects to the Second Floor and the Ground Level.
