To make your visit as safe and enjoyable as possible, you’ll need to follow our safety measures inside our venue, including wearing a face covering unless you’re exempt. Find out how we're keeping you safe. You no longer need to book a ticket to enter the museum or library.

We’re undertaking research with website visitors to find out some more about you and what you thought about your visit. This survey will take less than 10 minutes to complete. Thank you for your time!
