The remaining English castles became increasingly comfortable. Their interiors were often painted and decorated with tapestries, which would be transported from castle to castle as nobles travelled around the country. There were an increasing number of garderobes built inside castles, while in the wealthier castles the floors could be tiled and the windows furnished with Sussex Weald glass, allowing the introduction of window seats for reading. Food could be transported to castles across relatively long distances; fish was brought to Okehampton Castle from the sea some away, for example. Venison remained the most heavily consumed food in most castles, particularly those surrounded by extensive parks or forests such as Barnard Castle, while prime cuts of venison were imported to those castles that lacked hunting grounds, such as Launceston.
