Discover what to see in Margherita di Savoia: Europe’s largest salt flats, the historic Torre delle Saline, thermal baths and an Adriatic beach in Puglia.
Europe’s largest salt flats sit at the edge of the Adriatic, just north of the mouth of the Ofanto River — and they belong to a town of around 11,000 people that has built its entire identity around salt. Margherita di Savoia, formerly known as Saline di Barletta until 1879, is one of those rare places where a single industry has determined the landscape, the economy, the architecture and the food for centuries. If you are considering what to see in Margherita di Savoia, the answer begins and ends at the water’s edge.
The extraction of salt from these coastal lagoons predates the town’s current name by many centuries. The site was already operating as a significant salt-producing facility during the medieval period, when it was administered under the jurisdiction of nearby Barletta — a connection reflected in the settlement’s original toponym, Saline di Barletta. Salt was not a secondary commodity in southern Italy; it was a fiscal and strategic resource controlled directly by the state, and whoever managed these flats held real economic leverage over the surrounding territory. The Ofanto River, which meets the Adriatic just south of the saltworks, provided a natural boundary and a logistical corridor that made the site particularly valuable for inland distribution.
The renaming of the town to Margherita di Savoia in 1879 was a deliberate act of political symbolism: the settlement was rechristened in honour of Margherita of Savoy, who became Queen of Italy in 1878 upon her marriage to King Umberto I. This was the period of Italian unification’s consolidation, when many towns across the peninsula adopted names that signalled loyalty to the new royal house. The administrative transformation did not alter the economic reality: salt production remained the engine of the town, and the infrastructure built around it — including the Torre delle Saline, a watchtower constructed in the sixteenth century to monitor and protect the saltworks — continued to define the settlement’s physical character.
The twentieth century brought industrial-scale expansion of the saltworks and, eventually, formal recognition of their ecological significance. In October 1977, the saline were designated a State Nature Reserve by ministerial decree. Two years later, in May 1979, they received international status under the Ramsar Convention — the intergovernmental treaty on wetlands of international importance signed in Ramsar, Iran, in 1971. That dual designation transformed what had been purely an extractive industrial site into one of the most ecologically monitored wetland environments in the Mediterranean. The salt pans now function simultaneously as a working production facility and as a habitat for tens of thousands of migratory birds, including large colonies of flamingos.
The saltworks are the largest in Europe and rank second in the world by surface area. A complex of shallow evaporation basins stretches for kilometres along the Adriatic coast, turning shades of pink and rust depending on the mineral content and microalgae concentration of the water. The site operates as both a working industrial facility and a protected natural reserve classified under the Ramsar Convention since 1979.
Housed in a former salt warehouse directly adjacent to the sixteenth-century Torre delle Saline, this museum documents the full history of salt extraction in the area — from manual harvesting techniques to the mechanised processes of the twentieth century. Antique tools, archival photographs and reconstructed working environments give concrete form to an industry that shaped every aspect of local life for hundreds of years.
Built in the sixteenth century as a watchtower to protect the strategically vital saltworks from coastal raids, the Torre delle Saline is the oldest standing structure in Margherita di Savoia. Its position immediately adjacent to the salt museum makes it easy to visit both in sequence. The tower’s masonry reflects the austere military construction typical of Aragonese-era defensive architecture along the Pugliese coast.
Margherita di Savoia’s modern thermal spa facility draws on the brines and mineral muds extracted directly from the salt pan basins. The waters — technically called “acque madri,” the dense residual liquid left after salt crystallisation — carry a high concentration of minerals and have been used therapeutically for decades. The facility offers treatments ranging from mud baths to inhalation therapies, drawing visitors specifically for medical and wellness purposes.
The town’s coastline runs for several kilometres along a wide, flat beach of dark ferrous sand — the iron content gives it a colour noticeably different from the pale limestone beaches further south in Puglia. Approximately ninety bathing establishments operate along this stretch during the summer season, making the seafront the town’s primary public space from June through September.
Salt is not merely an industry here — it is an ingredient with local identity. The salt produced at Margherita di Savoia, harvested from the final crystallisation basins, is sold commercially and used across Puglia. In local cooking, it seasons fish pulled from the Adriatic and vegetables grown in the flatlands of the Tavoliere, the vast agricultural plain to the west. The proximity to the sea means that the table here is oriented towards seafood: raw shellfish, grilled orata and branzino, and the local preparation of baccalà are all staples in the town’s restaurants along the seafront.
Further inland from the coast, the food culture shifts towards the Tavoliere tradition — pasta dishes built on durum wheat, broad beans and cicoria, lamb from the Apennine foothills, and the olive oils and wines produced across the province of Barletta-Andria-Trani. The province sits within a wider Pugliese food economy that includes several DOP and IGP designations recognised by the Italian Ministry of Agricultural Policy covering local olive oils, wines and dairy products. For visitors, the most direct access to local produce is through the fish markets along the port and the trattorias concentrated near the thermal spa and the seafront.
Spring — specifically April through early June — is the most rewarding period for visiting the saltworks as a natural site. This is when migratory bird populations are at their peak, and the shallow basins begin their annual colour transformation as temperatures rise and evaporation accelerates. Flamingos are a consistent presence throughout the warmer months, but their numbers are highest in spring. The thermal spa operates year-round, which makes the town a viable destination in the colder months for visitors primarily interested in wellness treatments rather than the beach.
July and August bring the full weight of the Pugliese summer: temperatures routinely exceed 35°C, the beaches fill with Italian holidaymakers, and the town’s pace shifts entirely towards the coast. Those ninety bathing establishments operate at capacity. If the goal is the beach, this is when the town is most alive — though accommodation books up quickly and prices reflect the demand. September is a practical compromise: the sea remains warm, crowds thin after the first week, and the light over the salt pans takes on a lower angle that makes the colour variations in the basins easier to appreciate. The official Puglia tourism portal maintains updated event calendars for the province, which are worth consulting before travelling.
Margherita di Savoia sits on the Adriatic coast of northern Puglia, in the province of Barletta-Andria-Trani. It is not a difficult destination to reach from the main regional transport hubs, though it requires a degree of planning since it lacks a direct rail station of its own.
For current timetables and regional connections, Trenitalia’s official website provides updated schedules for the Barletta–Foggia rail corridor.
Accommodation in Margherita di Savoia is concentrated in two areas: the seafront strip, where hotels and holiday apartments cluster around and between the bathing establishments, and the town centre, which offers a smaller selection of B&Bs and guesthouses. For visitors whose primary interest is the beach or the thermal spa, the seafront zone is the logical base — walking distances to both are short, and the evening passeggiata along the lungomare is the town’s main social event. The thermal establishment itself is on the edge of the saltworks area, easily reachable from either zone on foot or by bicycle.
The accommodation offer skews towards mid-range hotels and self-catering apartments rather than boutique or luxury properties — this is a working coastal town, not a resort. Agriturismi can be found in the surrounding flatlands of the Tavoliere, offering a quieter base for those combining a visit to the saltworks with wider exploration of the province. The practical booking tip: if travelling between mid-July and mid-August, reserve several weeks in advance, particularly for seafront accommodation. Outside those peak weeks, availability is generally good and rates drop considerably.
The province of Foggia, which borders the Barletta-Andria-Trani territory to the west and north, offers a very different register of Pugliese experience. San Giovanni Rotondo, set in the Gargano highlands, draws visitors from across the world to the sanctuary of Padre Pio — a site of pilgrimage that has shaped the town’s modern infrastructure and economy in ways visible at every turn. Further south into the Apennine foothills, Deliceto occupies a ridge position above the Tavoliere with a medieval castle that overlooks the same flat grain-growing plain visible from the saltworks on a clear day.
Those who want to extend their journey into the deeper interior of Puglia will find the contrast with the coast sharply instructive. Cerignola, in the heart of the Tavoliere, is one of the largest agricultural towns in southern Italy — a place built on wheat and olives, with a history that includes the decisive 1503 Battle of Cerignola, one of the earliest engagements in European history decided primarily by firearms. At the other end of the regional register, the trulli landscape of the Valle d’Itria centres on towns like Cisternino, where whitewashed streets and conical stone roofs create an architectural language entirely unlike anything in the flat coastal north of Puglia.
