The Archive

The Planned Environment Therapy Archives and Special Collections are a unique, living resource that explores the history of therapeutic living and learning from 1900 to the present day.

Alongside the archive of the Mulberry Bush Organisation we are proud to be the custodians of over twenty other organisational archives in addition to materials collected from the groups and individuals who have shaped modern therapeutic practice. Together with our libraries, these internationally important papers provide countless opportunities for learning, reflection and research.
