Sacred Spring of Su Lumarzu

The monument, a small cult spring from the Nuragic period, consists of an atrium and a small cell where the vein of the spring is collected.
The paved rectangular atrium (5.15 x 1.80 m) has seating along the walls (height 0.30 m; width 0.40 m) and a small alcove. The masonry (height 2 m; width 3 m) consists of regular rows of carefully squared basalt blocks.
From the atrium one enters the small cell through an entrance with a trapezoidal light (0.65 m wide; 0.64 m high) obtained in a monolithic slab.
The small room (diameter 0.97 m; height 1.60 m), built of roughly worked but carefully joined blocks of basalt, has a "tholos" roof closed by a large horizontal slab.
In Christian times, a Latin cross was engraved on the underside of the end plate.
The water flows through a channel carved into the sill of the entrance to the spring to a drainage channel built under the floor of the atrium itself.
The settlement of the place lasted until late antiquity, as evidenced by coins from the fourth century. AD Found in the time of Taramelli while clearing the porch.Source: sardegnacultura.it/j/v/253?v=2&c=2488&t=1&s=21393
