The necropolis of Li Muri is an archaeological site located in the municipality of Arzachena. The necropolis, thought to be a product of the Arzachena culture and dating from the second half of the fourth millennium BC, is composed of five stone cists. Four of the cists are surrounded by stone circles that originally marked the limits of the mound of earth and rubble that was erected over the burial.
Bodies were interred inside the cists, probably individually (unlike in the rest of Sardinia where the graves were usually collective). The dead were accompanied by grave goods including pottery, stone vessels, hatchets and beads necklace of steatite and gemstones.
The architecture of the necropolis shows strong similarities with contemporary sites of Corsica, Provence and the Pyrenees.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
