In the PROVINCE OF PORTUGAL, the military power and resources of the order were exercised in almost constant warfare against the Moors, and Europe derived essential advantage from the enthusiastic exertions of the warlike monks in that quarter against the infidels. In every battle, indeed, fought in the south of Europe, after the year 1130, against the enemies of the cross, the Knights Templars are to be found taking an active and distinguished part. They were extremely popular with all the princes and sovereigns of the great Spanish peninsula, and were endowed with cities, villages, lordships, and splendid domains. The Grand Prior or Preceptor of Portugal resided at the castle of Tomar. It is seated on the river Narboan, in Estremadura, and is still to be seen towering in gloomy magnificence on the hill above the town. The castle at present belongs to the order of Christ, and was lately one of the grandest and richest establishments in Portugal. It possessed a splendid library, and a handsome cloister, the architecture of which was much admired. The houses or preceptories of the Temple in the province of Castile and Leon were those of Cuenca, and Guadalfagiara; Tine and Aviles in the diocese of Oviedo, and Pontevreda in Galicia. In Castile alone the order is said to have possessed twenty-four bailiwicks. In ARAGON the Templars possessed the castles of Dumbel, Cabanos, Azuda, Granena, Chalonere, Remolins, Corbins, Lo Mas de Barbaran, Moncon, and Montgausi, with their territories and dependencies. They were lords of the cities of Borgia and Tortosa; they had a tenth part of the revenues of the kingdom, the taxes of the towns of Huesca and Saragossa, and houses, possessions, privileges, and immunities in all parts.[33] They possessed likewise lands and estates in the Balearic Isles, which were under the management of the Prior or Preceptor of the island of Majorca, who was subject to the Grand Preceptor of Aragon.
