The old Gun pub is currently shown as closed on PuG as it was demolished in 2015 as part of the Spitalfields development..
But that development included building a brand new modern bar / pub run by the EastLondonPubCompany on the ground floor of the building on the same location and that pub opened last month..

As this is a complete new build pub I don't think it would be right to just reopen the closed pub listing but it may be better to keep that one as closed and add a new listing for

The Gun
54 Brushfield Street
E1 6AG

Is that possible ?
