Gràcia is where Barcelona's grid gives up. Walk north out of the Eixample and the chamfered corners stop, streets narrow to the width of one car, and balconies almost touch overhead. Every few minutes the walls open into another square — Plaça de la Vila de Gràcia under its clock tower, Plaça del Sol, Plaça del Diamant — each ringed with terrace tables under plane trees. The sound is chairs scraping, children, Catalan. The lanes bend because they follow torrents, the seasonal streams that once ran off the hills.
This was a separate town until 1897, one of the largest in Catalonia, built on mills, small workshops and the low houses their workers lived in. Its name comes from a Carmelite convent founded among fields in 1626, and Torrent de l'Olla and Torrent de les Flors keep the Catalan word for watercourse in their street names. It is now one of the densest quarters in the city, with small shops in old workshop doorways. For one week each August the residents close their own streets and hang handmade ceilings over them.
