I'm not at all sure that "Bank Alley" is the official name for this back alley in Tring, but as it leaves the High Street between the HSBC (formerly Midland) and NatWest Banks, this is the name by which everyone knows it. At the far end of this straight alley can be seen a wall, the alley then continues 90º left for a few yards/metres before turning 90º right and continuing along the back of the more modern buildings of SP9211 : The Walter Rothschild Zoological Museum, Tring eventually coming out on Park Street, where it continues as a footpath into SP9210 : Tring Park under snow/SP9210 : Tring Park in Summer
