Gone, but not forgotten.
Viv, I can't quite place the position of the shop as I would have expected Bull Street to be showing obviously next to the store.
The building of Lewis's progressed in this order. First they purchased to Corporation St Corner of Bull Street and rebuilt and refitted that (map1), next they acquired Berlin House and did the same there (map2) Lastly they purchased Newbury's department store and after a complete rebuild joined both stores together at each end of The Minories from the first floor to the roof giving us the store that most of us remember (map 3)
