Travel is not easy these days. Luckily we have youtube, social distancing networks and friends who share photos from their excursions and adventures. Here are some from the famous Bletchley Park, where Colossus was invented (and de-classified decades later). No wonder few know that this was actually the first computer, created by Tommy Flowers.
Colossus was recreated more than 50 years later from (human) memory, notes and imagination, blueprints destroyed long ago. It is on display in the National Museum of Computing, a separate entity from Bletchley Park museum (and therefore no photos of Colossus, just yet).
