About the Society:

The Twentieth Century Society is the national amenity society responsible for the study and protection of 20th/21st century architecture and design.

The Society was founded in 1979 as The Thirties Society. It is a scholarly and campaigning organisation which defends work of quality regardless of its style or school. It has over 2000 members and organises a programme of walks, lectures, tours and conferences in Britain and abroad. It is governed by an elected committee and is a registered charity.

We are also alerted to threats to buildings by other means, and carry out proactive casework.
