Metropolitan Borough of St Marylebone, Former metropolitan borough in the County of London, England
The Metropolitan Borough of St Marylebone was an administrative district within the County of London, covering areas such as Marylebone, Regent's Park, St John's Wood, and part of Fitzrovia. It sat north of Oxford Street and was made up of wide streets lined with stone terraces and large open green spaces.
The area was recorded in the Domesday Book of 1086 as a small settlement near the river Tyburn, and its name shifted over time from Tyburn to St Marylebone after a church dedicated to St Mary was built there. The borough itself was formally created in 1900 and was dissolved in 1965 when London's administrative boundaries were reorganised.
Harley Street is known across Britain as the address for private medical practices, a reputation built over many generations. Walking through it today, visitors still see the brass plates and quiet doorways that signal this long-standing role.
The area is easy to explore on foot, with Marylebone Road and the streets around Baker Street giving a good sense of how the district was laid out. The town hall on Marylebone Road, built in the early 20th century, is a useful landmark for orienting yourself.
The borough's coat of arms featured waves to represent the river Tyburn and flowers referencing a legend about lilies and roses found in the Virgin Mary's tomb. The church that gave the borough its name was originally founded by monks from Barking Abbey.
