Across Europe, there are many festivals of outdoor arts. One of the biggest and most spectacular is Fira Tàrrega. Every September, this tiny Catalan town in Northern Spain plays host to an extraordinary array of outdoor theatre, dance and circus. With roots dating back to the 1930s, Fira Tàrrega attracts thousands of artists, audiences and programmers from across the world. The annual trip to Tàrrega feels like a pilgrimage to the spiritual home of outdoor arts.
