Sanctuary de Sant Salvador, an old hermitage, 509m above sea level at the highest point of the Serra de Llevant was the senior house of Mallorca's monastic order and the last to lose its monks in 1992.
The walls were built in the 14th century to protect the town from pirates or invaders. There are walkways and a simple cafeteria along the walls, and a neoclassical church, which was built in 1832.
It is still a popular place of pilgrimage, flanked by two enormous landmarks - to one side a 14m stone cross, to the other a 35m column topped by a statue of Christ holding out his right hand in blessing. The views from the terrace take in Cabrera, Cap de Formentor and several other hilltop sanctuaries dotted across the plain. From the statue of Christ you look out towards the Castell de Santueri, a 14th century rock castle built into the cliffs on the site of a ruined Arab fortress.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
