Thàmus Network in Sassari: what it is, what it includes and how to visit it

Anyone visiting Sassari and looking for museums, monuments and archaeological sites will sooner or later come across the name Thàmus. It is not a single museum, but a cultural network linking some of the most important places for learning about the history of the city and its surrounding area.

The idea is simple: bringing together very different monuments under a shared identity, allowing visitors to travel through centuries of Sassari’s history, from the prehistoric sites of Monte d'Accoddi and Montalè to the medieval, Aragonese and nineteenth-century city.

The official tourism portal describes Thàmus as an itinerary for discovering Sassari’s monuments and cultural sites.

If you are planning a broader visit to the city, it may be useful to combine this route with our guide to the main places to see in Sassari.

The name itself also tells us something about the city.

Thàmus comes from the combination of Sassari’s ancient medieval name, Thatari, and the concept of a museum. The result is a brand designed to contain Sassari’s identity, culture and history in just a few letters.

The network’s graphic symbol is also inspired by the decoration on the ceiling of the entrance atrium of the Teatro Civico di Palazzo di Città, one of the central buildings on the route.

The municipality’s standard service currently identifies several main components of the network. Its distinctive feature is that they do not all belong to the same period, nor are they located exclusively in the historic centre.

Palazzo di Città and the City Museum

In the heart of corso Vittorio Emanuele II stands Palazzo di Città, built between 1826 and 1829 to a design by architect Giuseppe Cominotti.

Today it houses the City Museum and offers an in-depth look at the history of Sassari’s institutions, popular traditions, historical clothing, Carnival and, naturally, the Candelieri.

It also contains the small Teatro Civico, inspired by Turin’s Teatro Carignano.

Palazzo Ducale, the Duke’s Rooms and Cellars

Palazzo di Città is just a few minutes’ walk from Palazzo Ducale, now home to the Municipality of Sassari.

The Thàmus visit focuses mainly on the Duke’s Rooms, dedicated to the life and history of the Manca family, and the evocative Duke’s Cellars.

The latter lead into the building’s underground spaces, among ancient cisterns, wells, channels and structures dating from before the construction of the eighteenth-century palace.

For those who primarily want to focus on the city’s museum heritage, we have also put together a broader selection in our guide to Sassari’s museums.

Rosello Fountain

It is probably the network’s most immediately recognisable monument.

The Rosello Fountain, in its present form built between 1605 and 1606, is characterised by twelve spouts representing the months of the year and four statues dedicated to the seasons.

For centuries it was one of the city’s main water-supply points, and it remains one of the strongest symbols of Sassari’s identity.

Barbican of the Aragonese Castle

Beneath piazza Castello lies a part of Sassari that no longer exists above ground.

The Barbican belonged to the defensive system of the Aragonese Castle and was built between the fifteenth century and the beginning of the sixteenth century to adapt the fortress to the new firearms.

The archaeological route normally allows visitors to enter the fortification’s underground corridors. At the time of verification, on 22 August 2026, the site is temporarily closed due to high temperatures, pending conditions suitable for visits.

To truly understand the network, you have to leave the city.

Just a few kilometres from Sassari lies Monte d'Accoddi, one of Sardinia’s most unusual archaeological sites. The prehistoric complex features a monumental elevated structure with a ramp, often compared in form to the temple architecture of the Mediterranean and the Near East.

The site takes Sassari’s story back thousands of years, long before the birth of the medieval city. It is owned by the Direzione Regionale Musei Sardegna and managed by the Municipality of Sassari as part of the Thàmus circuit.

The other major prehistoric element is located in Li Punti, about seven kilometres from the centre.

The Domus de Janas of Montalè is an underground burial chamber carved into the rock, featuring a central cell surrounded by seven secondary rooms and interesting decorations, including carved bull protomes.

The complex is attributed to the Ozieri culture, with subsequent evidence of reuse during the Chalcolithic period. Visits are currently organised by reservation for groups and school parties.

This is where a distinction is useful.

The municipal page dedicated to the standard service lists Palazzo di Città, the Duke’s Rooms and Cellars, Rosello Fountain, the Barbican, Monte d'Accoddi and Montalè as its main components.

In other contexts, however, Thàmus takes on a broader cultural dimension. In the itineraries of Monumenti Aperti, for example, places such as Palazzo d'Usini, the municipal historical archive in the former Palazzo dell'Insinuazione and Palazzo Infermeria San Pietro have also been associated with the network.

Rather than an unchanging list of museums, it is therefore useful to imagine Thàmus as the system through which Sassari connects and presents an important part of its civic heritage.

Most of the urban sites are concentrated in the historic centre and are easy to reach on foot.

One possible itinerary is to start in piazza Castello, continue along corso Vittorio Emanuele II towards Palazzo di Città, reach Palazzo Ducale and finally descend towards the Rosello Fountain.

Monte d'Accoddi and Montalè, on the other hand, require travelling outside the centre.

Opening hours are not the same for all sites and may change depending on the season, public holidays or safety requirements. It is therefore advisable to check Turismo Sassari or contact InfoSassari before your visit, as it handles information and bookings for the network’s guided tours.

The real strength of the Thàmus Network is the opportunity to experience Sassari not through a single monument, but as a layered history.

In the course of a single visit, you can move from the rites and burials of prehistory to Aragonese fortifications, from aristocratic residences to the Teatro Civico, and finally to one of the city’s quintessential popular symbols, the Rosello Fountain.

For those visiting Sassari for the first time, Thàmus is therefore much more than a museum circuit: it is one of the best ways to understand how the city became what we see today.
