Geograph - photograph every grid square

A shrill siren sounds loudly at 1pm each day in the city centre, and this is the source - apparently (?) its original purpose was to indicate the time for cutlery workers to return from lunch and as a nod to this historical titbit, it still does. It is operated by H.L. Brown, the jewellers, who occupy the shop on whose wall it is mounted; they moved here when the building opposite was demolished (now occupied by Orchard Square shopping centre) and it moved with them.

The bells of the Town Hall clock, opposite it, struck 1 about half a minute later.
