Easily one of the best attractions I've ever visited. Start at the top of the historic venue (5th floor) with great views of the city plus a very amusing talk on the camera obscura itself and a chance to squish tourists (that will make more sense when you go) then take your own sweet time visiting the other 4 floors on the way back down. Each floor is dedicated to different aspects of the visual and there is tons to see and do. Although it's clearly good for children we were a group of 4 sober grown-ups and we all loved it. Plenty of opportunities to take photos and experience the exhibits "hands-on". Seriously good fun, even the stairs down to the quirky shop are musical. Brilliant.
