Between 1960 and 1961 the purchasing of lands nearby the sea in the north east coast of Sardinia has been very popular. Baron Zerilli-Marimò and Earl Cini bought the lands north of Olbia. For a while, their interests merged with those of Karim Aga Khan in the Costa Smeralda, with the opportunity of a single great investment plan. Soon they decided to develop two separate projects, one under the Consorzio Costa Smeralda and the other under the Consorzio di Porto Rotondo. The harbour and the village of Porto Rotondo are the result of the commitment of the Venetian Earls Nicolò and Luigi Donà delle Rose. In 1964 architects Pianon, Gamondi and Antonioli started the urban planning of the original Porto Rotondo and of the Sporting Hotel.
The design of Porto Rotondo began from scratch, as the land was unspoilt. The brothers Donà delle Rose called great artists, like Andrea Cascella and Giancarlo Sangregorio. They thought Porto Rotondo could become a centre of gravity for artists and intellectuals.
The centre of Porto Rotondo is Piazza San Marco, a round square between hotels and other buildings. Andrea Cascella designed it in accordance with the plan of arch. Pianon, using granite stone and concentric circles. The statue at the centre of the square improved perspective and helped hiding water drains. Architect Castellini and Sangregorio designed the harbour square. The idea was to link and to put in contact all important spots of the life of Porto Rotondo: the harbour, the main square, the church and the theater. Cascella engaged 30 stonecutters to cut the granite necessary to built the staircase from the square to the church of San Lorenzo. The Roman sculptor Mario Ceroli carved the sculptures inside the church. In 1980 Ceroli was also appointed of the works of the theater. The social network and relationships of the brothers Donà delle Rose were very important for the development of the village.
Porto Rotondo takes its name (Port Round) from the shape of its bay, naturally shielded from winds and waves. The marina came later, between 1978 and 1982. Nearby the marina towards Punta Lada and Punta Volpe cove and inlets interrupt the rocky coast.
The harbour can host 642 boats from 5 to 50 metres. 63 berths are reserved for transit mooring. Each berth has an individual safety mooring system.
