Monte d'Accoddi altar
The prehistoric altar unique in Europe, 30 minutes from Stintino
✽ 25 km from Stintino — 30 min by car
The so-called Nuraghe Monte d'Accoddi — the name is misleading, it is not actually a nuraghe but an altar-temple — is one of the most extraordinary and mysterious monuments of prehistoric Sardinia. Built between 4000 and 3600 BC by the peoples of the Ozieri culture, it is the only example in the entire western Mediterranean of a stepped construction of this kind: a truncated stone pyramid with an access ramp, structurally very similar to Mesopotamian ziggurats. It stands in open countryside between Sassari and Porto Torres, just twenty-five kilometres from Stintino — a half-day trip that takes you six thousand years back in time.
Six thousand years of history
The site has a two-phase building history. The first, in the middle Neolithic (4000–3600 BC), saw the construction of an initial sanctuary called the "red temple" because of the ochre that covered its walls. A landslide destroyed it and, around 3200 BC, the community built a much larger monument on top of the ruins: a trapezoidal platform twenty-seven metres wide and five metres tall, with a forty-one-metre access ramp. On top, rituals took place — libations, offerings, probably animal sacrifices — as attested by the remains of domestic animals and the cupules carved into the stones. The complex was abandoned around 1800 BC, at the start of the Bronze Age. Rediscovered in 1954 by the archaeologist Ercole Contu, it was restored in the 1980s and is now an archaeological site open to the public.
What you see on site
The visit follows a loop that you can walk on your own or with a guide. At the entrance, the reconstructed round huts of the Ozieri village. Just beyond, the monument appears: an enormous trapezoidal limestone altar with the long ramp climbing up to the summit. In front of the altar stand three red trachyte menhirs — vertical symbols perhaps linked to a fertility cult — an eighty-kilo perfectly smoothed limestone sphere, and the so-called "omphalos stone", a flat block with large cupules probably used for libations. On the esplanade, millstones, slabs with ritual engravings and remains of accessory structures. From the top of the ramp, the view runs across the Sassari plain — the same land the shepherd-farmers of the Ozieri culture cultivated six thousand years ago.
How to get there from Stintino
The easiest way is by car: from the villa, take the SP34 toward Porto Torres, join the SS131 "Carlo Felice" heading for Sassari, and shortly after exit at "Ploaghe–Monte d'Accoddi". Clear signs all the way to the site car park. Twenty-five kilometres in total, under thirty minutes. Free parking at the entrance to the archaeological area. There is no direct public transport from Stintino: a car — including a rental — is the only option. If you want to combine stops, Porto Torres (with the Basilica of San Gavino) is ten minutes away, and Sassari — the provincial capital with its medieval old town — fifteen.
Practical information
The site is open every day in summer, from 9:30 to 13:00 and from 15:00 to 19:00 — in winter only in the morning, with earlier closing. Monday is closing day. Admission is around €5 for adults, reduced for children and over-65s, free for under-sixes. The visit takes between forty-five minutes and an hour. At the entrance, a small visitor centre has interpretive panels in four languages. Our tip: come early in the morning or in the late afternoon. The site is almost completely exposed, with no trees, and the heat is felt during the middle of the day. Bring water, a hat and comfortable shoes. There are no architectural barriers for the platform, but the ramp has a slight slope.
