Visiting the Grotto

At present the grotto can only be visited by members of the public during the Twickenham Festival in June and Open House London in September each year or by special arrangement (see below). Dates and booking procedures for visits during the Festival are advertised locally in May and on this page.

Individual visits can be arranged in exceptional circumstances for accredited scholars and specialist historians. It may also be possible to arrange visits for other groups (up to 25). As the grotto is in Radnor House School, the availability of visits is subject to the School’s permission and cannot be guaranteed to meet your requirements.  Enquiries about arrangements for private visits should be made by contacting us here.  Please note that a donation to the Trust will be requested.

The Grotto is owned by Radnor House School. A map of the School’s location can be found here.

Openings in 2018

The next public openings will be in June 2018.  Subscribe to be notified when tickets are on sale.


The Trust and Radnor House School are looking for volunteers to assist on opening days, currently about four a year. We hope to open more frequently in future years and we will need a larger pool of people to call on.

If you are interested, please see our Volunteering and Jobs page. No special skills or knowledge are required.
