Back in the bullring: Richard Rogers's Las Arenas – in pictures

Las Arenas faces the Plaça D'Espanya, which was built for the Barcelona Exhibition of 1929. Behind it is the Parc de Joan Miró, formerly the location of the bullring's abattoir Photograph: Josep Ma Molinos/Rogers Stirk Harbour + Partners The rooftop viewing terrace has a magnificent 360-degree view of Barcelona. It has been a huge hit with the public Photograph: David Cardelus/Rogers Stirk Harbour + Partners Photograph: David Cardelus /Josep Ma Molinos/Rogers Stirk Harbour + Partners The service elements of the building are coded in colours that reflect Las Arenas's bullfighting history – red for the new structural steel, orange for toilets, purple for fire escapes and so on Photograph: David Cardelus/Rogers Stirk Harbour + Partners Photograph: Josep Ma Molinos/Rogers Stirk Harbour + Partners The ornate facade is in a style known as neo-mudéjar – a 19th-century revival of the Moorish architecture found in the south of Spain Photograph: David Cardelus/Rogers Stirk Harbour + Partners Photograph: David Cardelus/other Looking up at the vast main entrance arch Photograph: David Cardelus/Rogers Stirk Harbour + Partners Photograph: Josep Ma Molinos/Rogers Stirk Harbour + Partners New steel arms and a ring of concrete hold the base of the old facade in place.
