Beneath the soil layer where burials are placed is an extensive limestone formation, which is the source of most of the local building materials, which has supported drystone construction since medieval times.
The village of Gettlinge, as well as the precursor civilizations from Stone Age to medieval time, is primarily developed on a narrow low-lying ridge running north/south parallel to the Baltic coast.
The earliest settlers in Öland built early Stone Age wooden huts; the best examples of such excavated prehistoric dwellings are found a few miles to the east present village of Alby.
Archaeological excavations conducted over a period of years in the latter 1900s have revealed evidence of bear, marten, seal and porpoise, but also elucidate Mesolithic hunting and gathering technologies through discovery of bone spears, elk antler harpoons and flint.
The settlements of the Stone Age are key resources on Öland that led to the UNESCO designation of the Stora Alvaret as a World Heritage Site.
The Gettlinge Gravfeld is situated near the coast highway and contains some Bronze Age barrows as well as the more prominent stone ship burials, making it one of the largest gravefields on Öland.
Numerous grasses are found on this alvar including Meadow Oat-grass and Sheep's Fescue; as would be expected from the occurrence of orchids, many fungi grow on the Stora Alvaret such as Hygrocybe persistens and Lepiota alba.
