Monsanto sits on the edge of a mountain not far from Serra da Estrela. The town overlooks the valley below, affording sweeping views of the region from many vantage points. The ancient population carved dozens of narrow streets and passageways right through the center of the boulders, and those passages (just wide enough for a donkey to pass through) lead the residents upwards and downwards over the rocks and through the village.
The ancient people of Monsanto did not hack through the rocks to build their homes—the granite houses were built to accommodate the natural shapes of the boulders. Many residences squeeze and contort to the shape of the rocks. Semicircular roofs cap curved stone huts, stairways lead up and around the rock field, and entryways even open below boulders that are bigger than the houses that surround them.
This historic village still looks as though it’s been plucked from the past. The region was first populated in the 6th century BC by the Lusitanians as a walled settlement. Ruins from a Lusitanian castle from that era still stand in the town. Many of the homes still bear Manueline, or late Portuguese Gothic doorways (in the style of the infamous Tower of Belem in Lisbon) from the late 16th century.
Monsanto is a beautiful, living example of how people have adapted to preserve the integrity of their environment for hundreds of years. The village shows that environmental respect is a time-honored tradition!
