2Parc Güell, Barcelona, Spain

There’s no missing Parc Güell in Barcelona. The terrace at the top of the park is a great vantage point over the city, but Antoni Gaudí’s hypnotic artwork is the real reason to visit.

The winding Serpentine Bench uses tiles from a nearby factory while the famed lizard, or El Drac, guards the park (and is covered in Gaudi’s signature mosaics as well, of course). Opened to the public in 1926, the bursts of colours that make up Parc Güell is an example of the Trecandís techniques, a chopped effect often used in Catalan modernist art – and one which Gaudí perfected.
