Just a Doorway

Bricked and boarded up gateways and doors can be very intriguing. I've passed this little building on many occasions but only noticed this one fro the first time today. I've no idea what the place is or was used for but it's a very elegant and distinctive portal.

The building itself seems to have been built in two halves so perhaps it's as narrow as it is to be in proportion with the original small construction. I'll have to do some research.
