Archaeological Sites in Northern Sardinia: Nuraghi, Giants' Tombs & Sacred Wells near Olbia

1. What is a nuraghe — and why North Sardinia matters

Quick answer: A nuraghe is a Bronze Age dry-stone tower built in Sardinia between roughly 1900 BC and 730 BC and found nowhere else on Earth. Around 7,000 still stand. North Sardinia holds some of the latest and best-preserved examples — the Arzachena cluster alone has a full nuragic village, two of the tallest giants' tombs, and a sacred-well shrine 4 km from Olbia.

Nuraghi (singular: nuraghe) are circular towers made of large basalt or granite blocks fitted without mortar, often topped by smaller upper chambers and surrounded by a village of stone huts. The Italian Ministry of Culture counts about 7,000 still standing across Sardinia, of which the late-Bronze-Age complex of Su Nuraxi of Barumini in south-central Sardinia is the UNESCO benchmark — but it sits 3.5 hours south of Olbia, so for a guest staying in northern Sardinia it is a separate trip, not a day excursion.

The far north (the historical Gallura region and the territory around Olbia) is less famous than Barumini but holds three things you cannot easily see further south: the largest and best-conserved Gallura-type giants' tombs at Coddu Vecchju and Li Lolghi, the late nuragic village complex of La Prisgiona, and a working sacred-well shrine at Sa Testa on the outskirts of Olbia itself. Most are within 40 minutes of any RENTAL12 apartment or villa, which is why we built this guide as a north-tilted complement to the general Sardinia archaeology articles you will find elsewhere.

2. Nuraghe La Prisgiona — Arzachena

Quick answer: Nuraghe La Prisgiona is a late-Bronze-Age nuragic complex 7 km outside Arzachena, with a central tower, three lateral towers, a deep interior well still containing water, and the excavated remains of around 100 huts. Excavations have been ongoing since 1995. About 40 minutes from Olbia city centre by car.

La Prisgiona ("the prison" in Gallura dialect, named for the dense stone walls) sits in the Capichera valley just south of Arzachena, 7 km from the town and about 40 minutes from any of our Olbia apartments. The complex centres on a quadrilobed nuraghe — a central tower with three lateral towers fitted around it — and an internal courtyard with a corbelled well around 7 metres deep that has been continuously full of water since excavation began in 1995.

Around the central nuraghe, archaeologists have so far identified the remains of roughly 100 huts, including a "chief's hut" with stone benches around the perimeter and a circular hearth. Finds include grindstones, decorated pottery and a small bronze statue, displayed at the Olbia Archaeological Museum (see section 8).

It is one of the easiest nuragic complexes to read for a first-time visitor — paths are well-laid, signage is bilingual Italian/English, and the central tower can be entered. Allow about 75 minutes on site plus drive time.

3. Nuraghe Albucciu — Arzachena

Quick answer: Nuraghe Albucciu is a rare "platform" nuraghe — rectangular rather than the usual circular plan — built into a granite outcrop just outside Arzachena. It dates to the Middle-to-Late Bronze Age and sits about 35 minutes from Olbia. The combined ticket includes the Tempietto Malchittu, a 30-minute walk away.

Albucciu is interesting because it breaks the usual nuraghe rule. Instead of the classic conical tower, it is rectangular and was built into a natural granite shelter — a "corridor" or "platform" nuraghe in the archaeological literature, one of the older typologies, predating the classic tholos nuraghi. From the upper level there is a wide view across the Arzachena valley which by itself makes the short visit worthwhile.

Pair it with the Tempietto Malchittu (next section): same ticket, the walking trail between the two sites takes about 25 minutes through the typical Gallura granite-boulder landscape with cork oaks and lentisk.

4. Tempietto Malchittu — Arzachena

Quick answer: The Tempietto Malchittu is a Middle Bronze Age cultic building — one of the very few "megaron-type" temples in Sardinia, with a rectangular cella and a forecourt. It sits a 25-minute walk from Nuraghe Albucciu and is included in the same Arzachena Archaeological Park ticket.

Malchittu is the kind of site that rewards a deliberate visit. The footprint is small — a single rectangular chamber with a stone bench running along the inside wall, an apsidal end, and traces of a sacrificial hearth — but it is the only nuragic-era temple of its specific layout standing in Gallura, and the walk to reach it through the granite tafoni weathering forms is itself worth the half hour. Wear closed shoes and bring water in summer.

5. Tomba dei Giganti di Coddu Vecchju — Arzachena

Quick answer: Tomba dei Giganti di Coddu Vecchju ("Coddu Ecchju" in the local Gallura form) is a Bronze Age collective tomb famous for its 4-metre-tall central stele forming a curved exedra at the entrance. It is the tallest standing stele of its type in Sardinia, dated to around 2400–1600 BC, and 4 km from Arzachena.

A giants' tomb (tomba dei giganti) is a collective Bronze Age burial: a long stone-lined corridor up to 10 metres long where the dead were laid, fronted by a curved exedra — a semicircular wall of vertical slabs — with one tall central stele in the middle. The opening at the foot of the stele is small enough to be symbolic rather than functional.

Coddu Vecchju is the showpiece of the Gallura type. The central stele stands roughly 4 metres tall, carved with a horizontal moulding and a smaller "false door" at its base, and the exedra wall extends about 13 metres across. The corridor behind it, partially collapsed but still readable, was used over multiple generations.

The site is fenced and on a marked path from a small parking area. Allow 30 minutes for the visit; combine with Li Lolghi (10 minutes away) and Nuraghe La Prisgiona for a single half-day loop.

6. Tomba dei Giganti di Li Lolghi — Arzachena

Quick answer: Tomba dei Giganti di Li Lolghi is a second Gallura-type giants' tomb in the Arzachena cluster, slightly older and longer than Coddu Vecchju, with a 3-metre central stele and a 27-metre burial corridor. It is 10 minutes from Coddu Vecchju on the same combined ticket.

Li Lolghi pairs naturally with Coddu Vecchju and is sometimes overlooked because it is less photogenic — the stele is shorter and the exedra slightly more weathered — but archaeologically it is the more revealing of the two: the long corridor was built over the older base of a smaller Bonnànaro-period allée couverte, giving a clean stratigraphy of how a Bronze Age tomb was extended and re-extended over generations. The site is a 10-minute drive from Coddu Vecchju and on the same combined ticket.

7. Pozzo Sacro Sa Testa — Olbia

Quick answer: Pozzo Sacro Sa Testa is a late-Bronze-Age sacred well (water-cult shrine) on the eastern edge of Olbia, with an intact corbelled chamber, a 17-step staircase descending to the water, and a circular forecourt with stone benches. About 4 km from RENTAL12 historical-centre apartments.

Sacred wells (pozzi sacri) are one of the most striking features of late nuragic religion. They are not domestic — they are temples built around a spring or an artesian source, with a descending stone staircase, a corbelled chamber over the water, and a forecourt where bronze offerings have been recovered. There are around 40 known on the island. Sa Testa is the one closest to a major town and the easiest to reach without a car.

The Sa Testa site sits on the eastern edge of Olbia, on a small rise near the modern Lo Schenardi neighbourhood, about 4 km from the historical centre. The 17-step staircase descends roughly 7 metres into a perfectly corbelled tholos chamber where the water table is still active. The circular forecourt outside has stone benches and the holes for a wooden roof — bronze figurines and votive offerings have been found in this area, today displayed at the Olbia Archaeological Museum.

This is the site that should be on every Olbia visitor's itinerary, however casual. It is open-air, you can walk down into the chamber, and the proximity to RENTAL12's historical-centre apartments (Via Garibaldi, Via Cavour, Via delle Terme) makes it a practical 90-minute side trip rather than a full excursion.

8. Olbia Archaeological Museum — free entry

Quick answer: The Olbia Archaeological Museum opened in 2002 on a small islet in the harbour, with free entry for everyone. Its centrepiece is a hall of Roman and late-Roman shipwrecks recovered from the harbour mud, alongside nuragic bronze figurines and Phoenician trade goods. A 12-minute walk from the RENTAL12 historical-centre apartments.

The museum was built specifically to house the discoveries made during the dredging and modernisation of Olbia's harbour in the late 1990s. Twenty-four ancient shipwrecks were recovered from the harbour silt — most Roman trade vessels, but also late Roman and Byzantine ships, several of which had been deliberately scuttled to block the port against the Vandal raids of 450 AD. Two of them are partly reconstructed inside the museum.

Alongside the shipwreck hall, the permanent collection has nuragic bronze figurines from the Sa Testa sacred well and from Nuraghe La Prisgiona, Phoenician and Punic trade amphorae, Roman everyday objects (oil lamps, glass, coins), and a small medieval section. It is the single best free thing to do indoors in Olbia, and the air-conditioning is welcome on a 35°C summer afternoon.

9. Tomba dei Giganti di Su Mont'e s'Abe — Olbia

Quick answer: Tomba dei Giganti di Su Mont'e s'Abe sits about 20 minutes inland from Olbia, with the longest burial corridor of any giants' tomb in north Sardinia at 28 metres. It is less polished as a visitor site than the Arzachena tombs and remains open-air with no managed entry.

Su Mont'e s'Abe (sometimes "Su Monte e S'Abe") is the giants' tomb on Olbia's own doorstep — about 20 minutes inland from the city, in a quiet rural area. Its burial corridor is the longest in the region at 28 metres, built in opus isodomum of large worked granite blocks. The exedra is partially collapsed, but the stele base still stands and the whole monument is visible from the path. It is open-air, free, and signposted but not staffed — bring water and closed shoes.

10. One-day itinerary from Olbia or Golfo Aranci

Quick answer: A focused one-day archaeology loop from any RENTAL12 apartment covers four sites — Pozzo Sacro Sa Testa and the Olbia Archaeological Museum in the morning, then Nuraghe La Prisgiona and Tomba dei Giganti di Coddu Vecchju near Arzachena in the afternoon — about 90 minutes of total driving and 4 hours of site time.

If you prefer a slower pace, split this across two days and add Nuraghe Albucciu and Tempietto Malchittu (same combined ticket — pair them on a half day with the Capichera wine route nearby).

11. Tickets, opening hours, parking, what to wear

Quick answer: The Arzachena Archaeological Park (Geseco) operates a combined ~€10 ticket covering La Prisgiona, Coddu Vecchju, Li Lolghi, Albucciu and Malchittu. Single-site tickets are around €6. Hours are typically 10:00–17:00 in winter and 9:00–19:00 in summer. The Olbia museum is free.

Always check current ticket prices and opening hours on gesecoarzachena.it for the Arzachena sites and at the RENTAL12 reception desk on arrival — we update guest binders monthly. Parking is free at all five Arzachena sites and at Sa Testa; the Olbia museum has a small free lot 100 m from the entrance and is also reachable on foot from the old town across the harbour walkway.

Wear closed walking shoes, especially for Tempietto Malchittu and Su Mont'e s'Abe (uneven granite paths). In July and August carry at least one litre of water per person and avoid the 12:00–16:00 window if you can — most of these sites have little shade.

12. Where to stay — RENTAL12 apartments and villas

Quick answer: RENTAL12 operates 34 owner-operated apartments and villas in Olbia and Golfo Aranci, all within 40 minutes of every site in this guide. Our historical-centre apartments are closest to the Olbia museum and Sa Testa; our AZULIS villas in Golfo Aranci (Athos and Aramis, both with private pool) are closest to the Arzachena cluster.
