DH I have a trip to London next week and are wondering which museums/art galleries to visit. We both enjoy history, science and old buildings. I like art. We last went to the Natural History Museum and the Science Museum about 10-12 years ago but we've been to each of those 2-3 times so they aren't a priority this trip. My last (only?) British Museum visit, which I adored, was about 2 years ago. Also 2 years for the Tate Modern. Anything before that was at least 20-50 years ago. I've never been to the National Gallery, British Library, V&A, Greenwich, or anything else that I can think of right now. My only Tower of London visit was about 45 years ago(!) and I can't remember anything.
So, given that we have 1.5 days for sightseeing, I'd love some ideas of what to see/do. Please tell me what is brilliant and what isn't worth it. Thank you!
