Domus de Janas of Sedini, Archaeological site and ethnographic museum in Sedini, Italy.

The Domus de Janas of Sedini is an archaeological site featuring burial chambers carved into limestone rock formations. Today it serves as a museum displaying traditional farming implements and domestic items that illustrate daily life across different periods.

The necropolis was cut into rock in the 4th or 3rd millennium BC. Over the centuries the chambers were reused as a prison, an animal shelter, a shop, a party office and a private dwelling, and part of the medieval structure survives, with a hearth sunk into the rocky floor and spiral stairs carved from the living rock. The municipality acquired it in the mid-1990s.

The name Domus de Janas means "house of the fairies" in Sardinian, reflecting local folklore about these ancient burial chambers. Walking through the rooms, you see everyday objects that show how people lived long ago.

The site sits on the main street inside Sedini's historic centre, so it is reached on foot rather than by a country track. The rooms are cut into a single surface boulder, with a medieval section that keeps a hearth sunk into the rocky floor and spiral stairs carved from the living rock; expect uneven stone underfoot and narrow steps. The municipality acquired it in the mid-1990s and turned it into the permanent museum of Sedini and Anglona ethnographic traditions.

Locals call the rock "La Rocca", and it is considered the largest domus de janas in Sardinia because it was cut into a huge boulder lying entirely above ground, on the town's main street. Part of it keeps a medieval layout, with a hearth sunk into the rocky floor and spiral stairs carved from the living stone.
