Nearly 2 miles of medieval city walls surround York, making it the largest remaining defensive walls in England. Some of the wall is near roads and homes, but much has park and gardens along side.
The city takes great care maintaining the wall, and you can walk around the town on the wall. However, you can find flowers here and there.
The Romans first walled the city, and portions of their work still survive. In some places, the invading Danes, who next captured the city, expanded the circumference. The Anglo-Saxons expanded and built it even higher. The walk around the city is beautiful as well as a journey to the past.
