Boscobel Street is named after a nearby pub called the Royal Oak.
Boscobel House, Staffordshire and its Royal Oak tree became famous as hiding places of King Charles II after his defeat at the Battle of Worcester in 1651.
Charles’s adventure is commemorated by over 500 pubs named the Royal Oak.
The nearby Royal Oak was situated at 2 Princes Road. This pub was present from c.1830 and was demolished in 1898 to make way for the Marylebone Goods Yard, which is now the site of the Lisson Estate.
Boscobel Street was originally named Princes Street but inherited a new moniker in a mass London-wide street renaming where duplicate names were replaced.
