The village of Monsanto - Alcains, Portugal

The village of Monsanto is built among, and under, massive boulders and hangs over a mountaintop with beautiful views of the surrounding scenery. The location has been a strategic position since prehistoric times and the hill is crowned by the ruins of a Templar castle, partially destroyed in the 19th century. Strolling the narrow, cobblestone streets is fascinating, with its homes built into the rocky landscape, with doors into boulders.
