Visiting the Grotto

At present the grotto can only be visited 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.

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 2017

We will be open on three Saturday mornings during the Twickenham Festival which runs from the 9th to the 25th June. Book your tickets now with Eventbrite.

The Grotto will also be open on Open House London weekend on the morning of Saturday 16th of September. See the Open House website for more details.


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 send a message using our Contact page. No special skills or knowledge are required.
