This is the iconic Tourlitis lighthouse in the Hora of Andros, the only lighthouse in Europe that's built on top of a rock.
It's 7 metres high and was built back in 1887 but only started operating 10 years later, in 1897.
It's looking towards the East and if you want to take the shots you're seeing, then you need to wake up for the sunrise. Head to Nimborio beach and find the perfect spot for your shots. You can line up the sun and the lighthouse and take some incredible pictures!
