The attached Sarum Street structure, (lock-up), built from limestone ashlar with a slate roof, and so easily overlooked, was an overnight lock-up erected in 1820, once called ‘the Salisbury’. It has an iron ceiling, presumably to prevent prisoners from breaking out. A small interpretation plaque would be erected as part of the improvements.

Three differing bands of brickwork show how it had been repeatedly enlarged. Its size is evidence of the importance of the grain trade in Poole of yesteryear and its enormous internal beams characteristic of structures built for storage
