The Science Museum
Families flock to this museum, as do school kids taking part in field trips (380,000 visit as part of a school group each year). Founded in 1857 as part of the South Kensington Museum, the Science Museum has operated independently since 1909, with 12,000 scientific, technological, and medical objects on display, and more than 300,000 in its collection. Exhibitions are wide-ranging, from photography shows to an exploration of space travel. The last Wednesday of every month the museum hosts a late-night viewing until 10 p.m. It's only for adults and features pop-up snack and cocktail bars around the venue, as well as the ever-popular silent disco.
