I attended a tour of the above on Friday and here are some photos that I took. The first is of some medieval graffiti which are love hearts carved into the crypt where Kett and other prisoners were kept. These may well have been messages to loved ones in the prisoners' final days.
Here is some graffiti of a boat from the same crypt. It doesn’t seem certain whether the boats represented a vocation or whether they were a vessel of travel (e.g. escape or means of travel through purgatory), we will probably never know.
The final photo is a picture of the wall around Norwich. We are all aware that the wall didn’t extend to the area behind the cathedral and Bishop’s Bridge but I wasn’t aware that the gap in the wall was so large at St Martin’s Gate (top left in the photo) which in my view would make the city vulnerable to attack. Obviously the river was the defensive barrier in these areas but as we know from Kett’s rebellion, a committed force could get over the river. Anyway the other main purpose of the wall was for the collection of tolls and this along with the river performed an excellent perimeter for this purpose.
