Tower of Estorm Monument · Sant Esteve de la Sarga, Pallars Jussà, Lleida A circular tower from the 11th century, partly in ruins, crowning the walled village of Estorm, in the municipality of Sant Esteve de la Sarga, and part of the defensive line of the northern slope of the Montsec d'Ares. It still stands 12 metres high, with an outer diameter of 4.8 metres and walls 140 centimetres thick; the door opened at about five metres above the ground, and it probably had two more floors. To the south a small walled enclosure survives, which occupied the rest of the summit, with an 80-centimetre wall, and to the northwest an artificial ditch that made access difficult for the enemy. In 1099 Count Pere Ramon I of Pallars Jussà granted the district of Estorm to the canonica of Mur; from the late 17th century until the early 19th it belonged to the Portolà, barons of Castellnou de Montsec.
