Barcelona: City of Gaudi

Barcelona's Sagrada Familia has recently become the world's tallest church, and on the 100th anniversary of the death of its creator Antoni Gaudi, The Travel Show visits the basilica to meet the people who live and work in its shadow. Rajan Datar meets the architect tasked with overseeing the gargantuan project, the tattooist whose clients ask for the building to be inked onto their bodies, and joins a bride-and-groom getting married in the crypt of Spain's most popular attraction.
