It is now possible to walk the full length of the medieval curtain walls. This gives a fine view of the town and an impressive view of the cathedral. One of the towers, known as Cobb Hall, held the dungeons for condemned prisoners. They would be taken to the top of the tower and there publicly hanged.
The executed prisoners, both men and women, were buried by Lucy Tower, in unconsecrated ground. Their graves can still be seen.
From here we went on to see an original Magna Carta, which is kept at the castle. However, we were to be disappointed. The document cannot be kept on view all the time. It obviously needs to be carefully tended and protected. It was explained to us that it had gone for a much needed rest in a darkened room. I know the feeling!
Unfortunately, I was not able to visit the Bishop's Palace either, as it was closed for restoration.
