About the Gresham CollegeGresham College, founded in 1597 by the will of the merchant Thomas Gresham, gives free talks and lectures to the public.
Despite its name, it does not enrol students or award degrees but offers free to attend lectures to anyone who is interested.
The lectures generally take place in Gresham College's building in Holborn or at the Museum of London's lecture theatre.
Topics range from economics, maths, science, music and history.
Gresham College was also one of the first venues to routinely broadcast lectures online.
IMPORTANT - Although venues are reopening, their hours may differ from normal, and most now need prebooking before you visit.
