Our galleries are quietest on weekdays and weekend mornings. At busy times, particularly on Saturdays, you may need to queue for our temporary exhibitions.

We’re undertaking some research with website visitors to learn more about how people find access-related information provided by museums. This survey shouldn't take longer than 10 minutes to complete. Thank you for your time!
