Palau Güell, one of the first works of Antoni Gaudí, is considered one of the most significant buildings of the modernist architecture of Barcelona. In A day at Palau Güell, the urban sketcher Fabio Castro uses this technique to offer his particular vision of the different halls, rooms and areas that make up the palace and uncovering all the hidden Gaudí's stokes of genius.

«When I was a kid I already felt the need to express myself visually. At the age of sixteen I went on an amazing journey along the Quetzal Route and realised that sketching gave me more possibilities tan photography as it enabled me to reinterpret and explore reality. Once settled in Barcelona, sketching became a way of life and a medium to improve my skills. At present, I focus completely on understanding what I am sketching to extract its meaning and beauty. I enjoy while learning, and vice versa.» Fabio Castro
