Barcelona

Gregg heads to Barcelona, uncovering the city's artistic side in the incredible architecture of Antoni Gaudi, most famous for the Sagrada Familia, a large unfinished Roman Catholic minor basilica. The MasterChef presenter learns about the city's other artistic sons, while doing a self-portrait in the style of Pablo Picasso. He also visits the street festival in the Gracia neighbourhood, which culminates in the breathtaking castellers, or `human towers", and samples the array of back-street tapas restaurants.
