The Cosmos Illusion Museum sits on Dome Square, right in the Old Town, a few steps from the Cathedral. It is a compact, interactive space with more than thirty exhibits built around optical illusions and tricks of perspective: rooms that make people look tiny or giant, images that change as you move, and set-ups designed for photographs. Touching and posing are encouraged, and staff can help you find the best angles. It is open daily, from late morning until the evening, which makes it a handy rainy-day stop or an after-dinner activity, and it suits all ages. It is not a serious museum, but it is fun, central and easy to fit into an Old Town day.
How to visit: book a skip-the-line ticket and allow about an hour. Charge your phone before you go, because most of the fun is taking photos and videos in the illusion set-ups, and go with a companion so you can take turns.
When to go: weekday mornings soon after opening are quietest. Rainy afternoons and school holidays are busiest, so expect some waiting at the most popular exhibits. Because it stays open into the evening, it works well late in the day when other museums have closed.
Combine it: Tiqets sells a combined ticket with the House of the Black Heads, a few minutes away on the Town Hall Square, and the Cathedral’s noon organ recital is next door.
