The Knights Templar built a monastery complex here shortly after Lleida was taken from the Muslims in 1149. It was later expanded into a fortress in the 17th century. Today you can still see the original Romanesque Església de Santa Maria de Gardeny and a hefty tower. An imaginative audiovisual display (in Spanish or Catalan) lends insight into the monastic life of the Knights Templar.
This historic site is a 2km walk southwest from La Seu Vella.
