It is rather hard to imagine exactly what the life of these soldiers was like. It was a hard life, but in return for serving King and Country they received pay, food, clothes and in some cases a longer mortality rate. Have a look at the following pictures. Imagine being on sentry duty here.
There was barely enough room to turn around, no where to sit, no drinking facilities. It was blowy here on the day we visited. Imagine in the middle of winter.
There are still lookouts from the Castle, not military ones, but tourists and these little chaps!
