"A word to the easily offended, cover your eyes now: This is the world’s first museum comprised entirely of artworks considered so scandalous that they were banned, censored or withdrawn from public view. New to Barcelona’s arts scene since the end of 2023, spot it via bright-red flags (evoking smut-shop undertones) hanging outside the juxtaposed setting of a grand Modernista-era townhouse. Word is still getting out, so it’s enjoyably uncrowded, which is helpful as you’ll get the most out of the visit by lingering at each work and reading about the wider context. The free digital guide, accessible via QR code, contains everything you need to know. Continuing the cheeky theme, the store features hand-shaped candles flipping the bird, necklaces with the word “no”, banana vases, and mini lamps with Keith Haring illustrations. An hour gives you time to see everything, read most of the blurbs, and do a spin of the gift shop. Architecture buffs may want to spend longer admiring the building itself (called Casa Garriga Nogués by architect Enric Sagnier i Villavecchia), which has spectacular stained glass." - Gemma Askham
