MI5: Official Secrets
Visit our 5-star rated exhibition, made in partnership with MI5.
Please note that we are currently very busy, so you will experience a wait. The good news? We’ve extended the run until 23 November, giving you plenty of time to plan your visit. Top tips: Arrive early to avoid long queues. For a quieter experience, join us on Tuesdays or Thursdays, when we’re open until 19:00 — perfect for a relaxed evening exploration.
