Tapestries in London, fall 2026

I think you would have to contact whatever tour company you are thinking about using.

Which ancient tapestries are you interested in seeing? Are you referring to the Bayeux Tapestry? It will be available as a special exhibit at the British Museum beginning in September next year. Tickets are required, but have not yet gone on sale. You will need to monitor the website for an announcement. At a guess, that exhibit will be highly popular, with tickets in demand, so it might be wise to plan your London free time around whatever day you can get a ticket. I wouldn't hold my breath on tour companies including such an exhibit, but you could contact them directly.
