The tower of the Castelo Branco at the end of the blue hour with some fog at the high hilltop. The Miradouro do Castelo Branco is a viewpoint at the main island São Miguel of the Azores. From there you can see the village of Villa Franca do Compo, the Furnas Lake and the Atlantic Ocean. The tower looks like a medieval fortress but it is more recent and constructed with concrete. I used some flash lights to illuminate the insides of the tower.
