Evaluation work at Guestling Mill uncovered part of the town wall showing two phases of building (TR3293158475) . Phase one approx 45cm wide of large aggregate sandstone blocks in a light buff sandy mortar. The slim width of this wall may be due to it being cut back prior to the next phase of construction. This was 1.1m wide with smaller sandstone blocks along with bricks, flint and occasional chalk blocks set in mid grey-brown mortar. The east end of this section of the wall had been cut away a rre-surfaced with Sand wich bricks. It is suggested that this may be evidence of a portal or postern gate giving access to the Guestling following the French raid of 1455.(1)
