In 1962, Prince Karim Aga Khan IV unveiled his audacious dream for Costa Smeralda: a paradise of luxury amid Sardinia's rugged shores, centered in Porto Cervo
Porto Cervo — Aga Khan's Lost Blueprint
You are an urban planner commissioned by Karim Aga Khan IV in 1962 on the Costa Smeralda, Sardinia.
Your mission is to find the original plans for a Porto Cervo site
Delve into Karim Aga Khan IV's visionary dream in Porto Cervo, at the heart of the Costa Smeralda, a project that redefined luxury tourism in Sardinia.
The story that haunts this land
Your journey begins at the Piazzetta di Porto Cervo, the nerve center of the Costa Smeralda developed by Karim Aga Khan IV starting in 1962. Designed by Luigi Vietti and completed in 1964, this square was the convergence point for essential services, from shops to restaurants, before the consortium's sale in 1994. It is here that the first stones of the project were laid, symbolizing the vision of an integrated luxury destination, rooted in the tourism heritage of Sardinia and Olbia-Tempio.
Next, you head towards Marina di Porto Cervo, also founded in 1962 by Karim Aga Khan IV. This port, with 700 berths, quickly became one of the best-known in the Mediterranean during the 1960s-1970s. It is home to the prestigious Yacht Club Costa Smeralda, an institution that gained international renown and remains a key element of Porto Cervo's nautical infrastructure in 2026. Mediterranean coastal architecture reveals itself in all its splendor here, attracting an international jet-set.
Your exploration leads you to the Chiesa di Stella Maris, a religious edifice integrated into Porto Cervo's urban plan, completed in 1964 by Luigi Vietti. Built according to the principles of preserving natural heritage and local architecture defined by the Costa Smeralda Consortium's Architecture Committee, this church represents the fusion of tourist modernity and Gallurese architectural tradition, a striking example of the care taken in every detail of the Costa Smeralda's development.
The route then takes you to the Hotel Cala di Volpe. Designed by architect Jacques Couelle, this hotel was one of the first buildings completed in the Aga Khan project in the early 1960s. Remaining one of the iconic sites of the Costa Smeralda, it is a symbol of luxury architecture integrating local resources, such as granite and wood from Gallura. It embodies the spirit of Karim Aga Khan IV's integrated tourism development, a model for Sardinia's tourism heritage.
Finally, your investigation leads you to the Pevero Golf Club, a sports establishment created as part of the Costa Smeralda's integrated tourism development. Part of the high-end leisure infrastructure alongside the Tennis Club and the Marina, it remains operational in 2026 as an element of Porto Cervo's excellent tourist complex. This walking thematic circuit will have allowed you to reconstruct the Aga Khan's lost plan, revealing the decisive steps in the creation of this world-renowned destination, a true jewel of Olbia-Tempio.
