Kelvingrove is the kind of museum that makes you reconsider what museums are for. The building alone, red sandstone, Spanish Baroque, sitting in Kelvingrove Park, is worth the visit, but inside it's 22 galleries spanning natural history, arms and armour, Rennie Mackintosh, Impressionists, and Salvador Dalí's Christ of Saint John of the Cross, which has its own room and still stops people cold.
Everything is free, everything is very good, and the daily 1pm organ recital in the central hall is one of Glasgow's best-kept open secrets. Come at lunchtime, stay longer than you planned.
