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:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
