It took over 500 years, from the 13th century to the 19th century, to build this Cathedral with volcanic stones. Inside you can find unique stained-glass windows and wall paintings, and if you walk up the Bayette tower you will get the best panoramic view of the area.

The Château d'Eau, a 19th-century brick water tower located on the banks of the Garonne river was once used to supply 90 fountains. It has been repurposed as a photography gallery hosting exhibitions and a library selling books on photography.

If you could draw an almost perfect Robinson Crusoe style beach, Dolly would definitely be a contender. Natural food supplies, shelter, and a source of fresh water would keep most castaways happy, and this beach has been known to do just that. As you arrive, especially if you are the first person of the day, you may be drawn to the turtle tracks in the sand. You can follow them until you find the signs of a nest. Both hawksbill and green turtles have been spotted. At the northern end of the beach, the hills are marked by fantastic rock formations with plenty of resident seabirds. More interesting, though, are the sea-level rock pools. Waves crash over the golden-toned, stony reef edges, which doesn't discourage marine life. Red algae and small hard corals paint different colours across the surfaces, while small fish dart about between the pools. Tiny moray eels hunt in ankle-deep water, and if you stay still they will swim up to you. The opposing end of the beach has slightly deeper pools to explore. Depending on the tides, these allow safe, shallow swimming. Going over the rocks to the sea isn't advised, as currents can be strong.
