The number sign on this door is so pretty that it caught my eye. It’s in Woburn Square in Bloomsbury, London. Named after the Duke of Bedford’s family seat – Woburn Abbey in Bedfordshire – the houses in the square were built between 1829 and 1847 and are now mostly occupied by University College London. Number 18 houses the Social Science Research Unit. There’s still a small garden in the centre of the square. To my delight, I discovered that Camden Council have run a project documenting the doors of Bloomsbury, including those in Woburn Square – worth a look for some fabulous Georgian gems.
