Great Yarmouth town has one of the best preserved and most complete Medieval town walls in England. Dating from 28 September 1261 when King Henry III granted Yarmouth the right to build a town wall. Large sections of these walls still survive today. Much of the Grade II listed wall still stands today, sometimes haphazardly interspersed with modern day buildings, however some of the most impressive remains are outside the Time and Tide Museum and along Blackfriars Road.
