THE CITY OF LONDON ARCHAEOLOGICAL SOCIETY (COLAS) was founded in 1966 to encourage an active appreciation of archaeology, particularly in the City of London, where many of its members have worked with the Museum of London on major excavations.

Our connection with the Museum and its archaeological service continues to the present day. COLAS encourages active involvement with archaeology and historical research. COLAS is playing a significant part in the Thames Archaeological Survey.

COLAS is a Registered Charity and is affiliated to CBA, Rescue, LAMAS and SCOLA.

This gold Noble, an extremely rare coin of Henry IV, was discovered by a COLAS member on a site near Cannon Street station.
