Monsanto e Idanha-a-Velha is a civil parish in the municipality of Idanha-a-Nova, Portugal. Thanks to its fine collection of ruins, the village of Idanha-a-Velha has some of the country's most important archaeological sites. It stands in a place where a Roman city once lay, the capital of Civitas Igaeditanorum (1st century BC) and later the episcopal seat during occupation by the Suebi and Visigoths.
It was occupied by Muslims in the 8th century and taken back by Christians in the 12th century. It was donated to the Knights Templar in the 13th century and still has traces of different ages that attest to permanent occupation by various civilisations. Perched on a hilltop that oversees all the surrounding horizons, the village of Monsanto has a unique charm that has earned it two titles in the 20th century – the Most Portuguese Village in Portugal in 1938, a title awarded by the Portuguese Secretariat for Propaganda under the Estado Novo regime, and Historical Village in 1995.
Monsanto is one of the region's main tourist attractions and offers visitors a unique experience. It was granted charters by King Afonso Henriques, King Sancho I, King Sancho II and King Manuel. The oldest part is also the highest point, where the Knights Templar built a wall with the donjon.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
