Tenby was built by the Earls of Pembrokeshire in 1264 with the specific aim to protect the town from the Welsh rebellion. The construction had been so well done that the walls are still standing today bearing silent testimony of a glorious past. The first time historians talked about Tenby was around 1093 when it had become a Norman colony.The walls of ancient Tenby stand confirmation of Tenby’s initial boundaries, which were erected in 13th Century and remodified in the 15th Century.
