The walkways you see would have enabled the troops to move rapidly between the towers.
In Conwy there is what is claimed to be 'The finest preserved Elizabethan house now surviving in Britain'. The house is called Plas Mawr, and it was built for a wealthy Welshman Robert Wynne as a way to show his status. It was built by between 1576 and 1585.
Visitors would be greeted in the main court yard. Moving through the house, you can see by judging by the size of the beds, and the door ways they were not very tall back then. It was interesting place to visit to see what life was like back in those olden times.
