The La Seu Vella – Old Cathedral of Lleida is situated atop the Lleida hill. The decision of King Philip V of Spain changed this Cathedral into a military citadel in the year 1707.
A Paleo-Christian and Visigothic cathedral previously used to occupy the site. The Cathedral chapter, in 1193, ordered the construction of a new edifice. Count Ermengol VII of Urgell and King Peter II of Aargon laid the first stone in the year 1203.
On the 31st of October 1278, it was consecrated to Virgin Mary, but it took as late as the 14th century to complete the cloisters.
