“Sa Nitja. Gestión del Patrimonio Mediterráneo”, a Non-Profit Association. In 1993, the association "Sa Nitja", founded by a multidisciplinar team directed by the archaeologist Fernando Contreras, prepared the project to create the “Ecomuseum de Cap de Cavalleria" in the harbour of Sanitja . And since then, the association has carried out several activities to set the foundations of a new cultural initiative.

“Sa Nitja. Gestión del Patrimonio Mediterráneo” is a cultural association, registered in line with the Associations Law 191/1964 (passed on December 24), with the stated goals to protect, preserve, investigate and make known the cultural heritage. It scope of action is the territory of the Spanish State .

In brief, the association was founded in 1992, after the Fundació “La Caixa” awarded a grant to invigorate the archaeological heritage in the Roman city of Sanisera . In 1996, the European programme Leader II awarded the project a new grant to renovate the Santa Teresa building and prepare an exhibition room, so the public could know and enjoy the territory around Cavalleria by means of an Ecomuseum.
