Park Güell entrance pavilions, Barcelona

The two entrance pavilions of Park Güell, seen from above with the city and the sea behind them. The park began in 1900 as Eusebi Güell's plan for a hillside housing estate of about sixty homes; only two houses were built, work stopped in 1914, and the city opened the grounds as a public park in 1926. Look at the roofs, which drip with white broken-tile icing like gingerbread houses, and at the tall checkered spire on the right-hand pavilion.
