Barcelona's architectural treasures span 2000-plus years. Towering temple columns, ancient city walls and subterranean stone corridors provide a window into Roman-era Barcino. Fast forward a thousand years or so to the Middle Ages by taking a stroll through the shadowy lanes of the Gothic quarter, past tranquil plazas and soaring 14th-century cathedrals. In other parts of town bloom the sculptural masterpieces of Modernisme, a mix of ingenious and whimsical creations by Gaudí and his Catalan architectural contemporaries. Barcelona has also long inspired artists, including Pablo Picasso and Joan Miró, both of whom have major Barcelona museums devoted to their works.
