A Summer by Ancient Ruins

 I took this picture during my vacation in Europe. It's an ancient castle and what's very interesting and clever is that the people that built this also built other castles, like this one, in certain areas around the island, but not without reason-- All the castles were built to be within view of each other, so in the case of an attack on one of the castles, they would be able to signal the others. This way there would be time for preparations to be ready for battle. A great strategy back in ancient/ medieval times and a beautiful, picturesque scene today.
