The Fan Museum in Greenwich is a spot dedicated to all things fans - not the sports kind, but the fancy handheld ones! It's been open since 1991 and is the only place of its kind in the world. They have had 85+ temporary exhibitions, typically changing every few months, which have covered a breath-taking variety of fan-related topics. You can check out their collections, attend fan-making workshops, and even hire out their Orangery for private events. Plus, they've got an online shop with unique gifts. So, if you're into history, culture, or just want to see some really cool handheld fans, this place is definitely worth a visit!
