Romanzesu is an archaeological site that is located near Bitti, Nuoro Province, Sardinia.

It consists of a Bronze Age nuragic sanctuary village of more than seven hectares.

The site includes a holy well, one hundred huts, two megaron temples, a rectangular temple or Heroon, an elliptical amphitheater, and a large labyrinth structure.

The name Romanzesu probably derives from the presence of Roman remains.

During the 2nd-3rd centuries AD, the area was occupied by the Romans.
