The Templar Castle was built at a strategic point to defend the territory and support the conquest beyond the Tagus River. Construction began in 1160 under the Templar Master D. Gualdim Pais. The north wing and higher ground housed the Templar Palace, with two pillars: to the east and at its highest point, the citadel with its rectangular control tower, and to the west, the fortified religious temple—the Templar Charola. Several towers and turrets are located along the extensive wall. The entire outer perimeter of this wall was protected by a rampart—a stone wall simulating a hill at the base, thus impeding the advance of assault engines, sentinels, and climbers. The wall, towers, and quadrangular and semicircular turrets contain rectilinear loopholes and broad battlements. The various military-architectural solutions undoubtedly originate from the Middle East, where King Gualdim Pais stayed for five years during the Crusades. The Charola was probably built or completed shortly after the fortifications and is intended to commemorate the Holy Sepulchre and Solomon's Temple. This castle was also the headquarters of the Knights Templar in Portugal. https://opctj.pt/castelo-templario-charola-e-convento-de-cristo-de-tomar/ The castle complex, with its walls and extensive gardens, is open to the public free of charge.

Built from 1554 onwards, the imposing building is considered a masterpiece of the European Renaissance. The fountain at its very center is fed by the waters of the Aqueduct of Pegões. King John III had it built outside the castle walls. Adjacent to the monastery church, the main cloister flanks the south façade of the Manueline nave, with which his father, King Manuel I, had already expanded the existing Templar church.

Tomar Castle is a castle in Portugal, where it is classified as a national monument. The Convento de Cristo was built within its walls. The castle was built by King Afonso Henriques around 1160 in a strategic location, on a hill and near the Nabão River. It has an external defensive wall and a citadel (alcáçova) with a tower inside. The keep, a central tower with residential and defensive functions, was introduced into Portugal by the Templars, and that of Tomar is one of the oldest in the country. Another innovation introduced into Portugal by the Templars (learned from decades of experience in Normandy and Brittany and elsewhere) are the round towers in the outer walls, which are more resistant to attack than the square towers. When the city was founded, most of its inhabitants lived in homes located within the castle's protective outer walls.
