Monsanto is a medieval village that is located in the municipality of Idanha-a-Nova, District of Castelo Branco, Portugal. It is located in eastern Portugal, not far from the border with Spain, giving it a strategic location in medieval times. A Knights Templar fortress was constructed on the highest point of the town, but this was destroyed in an explosion in the 19th century.
In 1938, Monsanto was given the distinction of being “the most Portuguese village of Portugal,” during a government sponsored competition.
Monsanto is famous for its boulders. The first settlers built small houses on the hilltop, wedging them between and under the boulders that were far too heavy to be moved. These small stone houses remain, creating one of Portugal’s most unique and charming towns to visit.
Monsanto is also a filming location for Season 1 of the HBO House of the Dragon series.
