‘It’s an image of how summer holidays should be’: Antonio Heredia’s best phone picture

The photographer was drawn to the colours and the geometry at his hotel in a national park in southern Spain

Antonio Heredia arrived at Hotel de la Naturaleza in south-east Spain while it was shrouded in darkness. It was past midnight, and Heredia and a colleague had spent the day filming a story about one of the last remaining lighthouse keepers in the country.

Mario Sanz is based in Mesa Roldan lighthouse, in the national park Cabo de Gata-Nijar, but he's one of just 15 still on duty in Spain. The other lighthouses are operated remotely with computers now. We finished the assignment and drove to this hotel. The roads were narrow and without lights, and we almost got lost."
