It is commonly thought that the inside of castles were very similar to the outside – grey stone – as the entire structure is made of the same material. However, our modern perceptions are not necessarily correct. The walls – both inside and out – of the castles would have been covered with plaster and then whitewashed. Then, using the available pigments from the area, paint could be made to paint designs on the walls and ceilings. Certainly, this is seen on the outside walls of the Fortress and this knowledge shines a different light on what we think life was like – at least for the wealthy – in the medieval ages.
