Why is there a stone relief of Grace Kelly on the wall of Seville Town Hall and how can you track down the railway from the Ibero-American Expo of 1929? Where might you find the legacy of Christopher Columbus' son, a medieval Jewish cemetery in a car park, the oddest of barbershops, forgotten souvenirs from the Guadalquivir steamboats, Masonic symbols in a church, the last remaining vestiges of the Andalusian pavilions from the '29 Expo, a little- known Modernist electric power station, an example of the Nazi Enigma machine, a collection of Chinese and Japanese art in a Renaissance mansion or the pillars of a medieval synagogue? Far from the crowds and the well-worn clichés, Seville still has many hidden gems it only reveals to locals and visitors who head off the beaten track. An essential guide for those who thought they knew Seville well or are seeking to discover another side of the city.
