Many of the features of the old fort were lost during the Lutyens renovation but if you delve a little deeper and don't accept what you see in front of you, parts of the old building can reappear before you.
In the Dining Room, for example, Lutyens created a new fireplace, laid a distinctive herringbone brick floor and carved out a huge window bay with tracery window in stone. He left untouched a bread oven and salt hole from the soldier's time (probably dating from the 16th-century) along with the low vertical walls which are about as old as anything in the Castle. The vaulted ceiling, installed in the 18th-century to bear the weight of a new gun battery above. The Dining Room stands as the best surviving example in the house of building work from all periods of development.
Throughout the rest of the Castle, other features can be found from the old fort. All that is required is a little imagination, a copy of the room sheet and perhaps a chat with one of our helpful volunteer Room Guides.
