Ayutthaya/The Old Prison/U Thong Road.
The only reason you would come here is for the parking, as it is across the road from the Chinese Market, also going through the Chinese Market you will find the jetty to rent small boats which is the only reason we came to see the prison, this prison they also used to execute the prisoners and locals believe that the crows are reincarnated prisoners, personally I think it more likely they are the reincarnated executioners, not that I believe in that rubbish I might add, anyway all that is left of the place is a Chedi and a few watch towers.
