St Marylebone

Former parliamentary and metropolitan borough of London, England, now part of the borough of Westminster. It is a mainly residential neighbourhood.

History St Marylebone was originally the village of Tyburn, and became St Marylebone from the dedication of a church in the 15th century near the River Tyburn (St Mary-at-the-Bourne). Two manors, Tyburn and Lilestone (Lisson), appear in the Domesday Book 1096.

Marylebone Gardens flourished from 1650 until 1778 when they closed owing to the spread of building northward to the New Road (Marylebone Road) in 1757. Beaumont Street and Devonshire Place now cover its site.

Cavendish Square, built in 1717, was the first development of St Marylebone as a fashionable suburb. By 1780 all the Harley-Oxford estate was laid out. The Portman estate on the west, built between 1760 and 1810, and the crown estate (Regent's Park), 1815–30, followed. Finally St John's Wood became London's first garden suburb when the Eyre estate was built up between 1830 and 1850.
