St Giles Circus is a road junction in the St Giles district of the West End of London at the eastern end of Oxford Street, where it connects with New Oxford Street, Charing Cross Road and Tottenham Court Road. It is near to Soho, Covent Garden, Bloomsbury and Fitzrovia. The word Circus is used although the buildings around the traffic junction are not all rounded, as with for example Oxford Circus.
From the Middle Ages until the fifteenth century, gallows were located at St Giles Circus alongside a cage for prisoners. The area was an infamous rookery until it was cleared in the mid-19th century with the creation of New Oxford Street parallel to St Giles High Street by clearances.
Tottenham Court Road tube station was opened in July 1900 as part of the Central London Railway, with the platforms under Oxford Street to the west of St Giles Circus, and the station opening on the south west side of the circus, on Oxford Street. The Charing Cross, Euston and Hampstead Railway joined the station with what is now part of the Northern Line in September 1908, with station entrance on the south east side of the circus. The main station ticket hall was later moved underground, built below the circus in the 1920s.
