Marmilla is a historical region in the southern part of Sardinia, Italy. It is characterized by its gently rolling hills made of trachyte and basalt, which contrast sharply with the flat plains filled with vineyards and orchards.
The region's main town is Sanluri, which is notable for its medieval castle, the Castello di Sanluri. The castle is one of the few in Sardinia to remain in perfect condition, and it now hosts a museum which exhibits artifacts discovered in the local area.
Marmilla's economy is mainly based on agriculture, with cereals, olives and vines being the most commonly grown crops. It's also known for its local crafts, in particular its traditional Sardinian carpets.
The area is also home to the Giara di Gesturi, a high basalt plateau noted for its wild horses, the last wild horse population in Europe. The Giara is a destination for trekking and nature walks, with several archaeological sites scattered about the plateau.
Marmilla is particularly famous for its archaeological sites related to the Nuragic era, a civilization that existed in the region from the Bronze Age to the Roman era. The most important of these is the Nuraghe of Barumini, a complex ancient megalithic edifice which is now a UNESCO World Heritage Site.
