Castle of Monsanto

Castle of Monsanto (Castelo de Monsanto) is a medieval Knights Templar fortress crowning a rocky hill in the municipality of Idanha-a-Nova, in Portugal's Castelo Branco district. Its ruins merge with the granite boulders among which the village of Monsanto is built, making it one of the most photogenic strongholds in central Portugal.

Who built the Castle of Monsanto?

King Afonso I of Portugal granted the lands around Monsanto to the Order of the Templars. Gualdim Pais, the Order's master in Portugal, organised the defences here, and a fortress stood on the hill by 1171. The castle belonged to a chain of strongholds protecting the kingdom's frontier against incursions from the Kingdom of León and the Almohad Caliphate. Other Templar castles of the same era, such as Almourol, Pombal and Tomar, served a similar purpose.

What does the castle look like today?

The castle is a permanent ruin. In 1815 (some sources say a year earlier) a gunpowder magazine exploded inside it and destroyed much of the structure. Still standing are the defensive walls, a lookout tower and the remains of the Church of Santa Maria within the enclosure. Some walls rise directly from the bedrock, so it is hard to tell where masonry ends and natural boulder begins.

Why visit?

The views are the main reward. The castle sits high above the wide plains of Beira Baixa, and on a clear day the outlook stretches towards Spain. The walk up from the village centre usually takes 20 to 30 minutes each way, along narrow cobbled lanes between houses squeezed under enormous blocks of granite.

The village itself was named the "Most Portuguese Village in Portugal" in 1938 by the Estado Novo regime's propaganda secretariat, and in 1995 it joined the Historic Villages of Portugal network. The castle is its principal monument.

Practical tips

Go in the morning or late afternoon, when it is cooler and the light brings out the texture of the granite. There is little shelter from sun and wind at the top, so bring water and a light jacket. The castle is an open hilltop ruin, and the rocks can be slippery after rain. Leave time to wander through the village too: its houses, small churches and alleys form a single landscape with the castle.
