From the Neolithic Carnac stones of Brittany to the thousands of Roman and Greek ruins across the Mediterranean, Europe has an incredible array of ancient ruins to explore. We’d love to hear about your favourite sites – places where the past feels within touching distance, whether it’s a prehistoric cave painting, a beautifully-preserved mosaic, or the ruins of a temple.

If you have a relevant photo, do send it in – but it’s your words that will be judged for the competition.
