Underground Heritage Information
Southgate station listed as a building of national significance
Architects: Adams, Holden & Pearson. 1933
Southgate station opened on 13 March 1933 on the second phase of the northern extension of the Piccadilly line from Finsbury Park to Cockfosters.
The station is one of the best known of the many stations Charles Holden designed for London Underground. The station building is circular with a flat projecting concrete roof. Externally, the flat roof of the raised central section appears to be supported by nothing more than a horizontal band of windows that provide natural light to the interior, although it is actually supported from a central column in the ticket hall. The whole building is topped by an illuminated feature resembling a Tesla coil, The station is externally flanked on two sides by circular reinforced concrete waiting shelters including the "bullseye" roundels which were designed by Stanley Heaps.
The station retains much of its original decorative style. The two escalators have the original column lighting which has been adapted to meet modern lighting requirements, while bronze panelling is in evidence throughout the station.
In 2007 the station was extensively renovated to bring the station back to its former glory. The tiles were renewed using the original colour scheme while sensitive repairs were undertaken to the ticket hall area. In recognition of this renovation the station gained a National Railway Heritage award in 2008.
The station was originally Grade II listed in February 1971 and subsequently Grade II* listed in 2009.
