History
Before colonisation the coastal lagoons and hills were used by Charrúa, Guenoa and other hunting peoples, and the region later became the front line between Spanish and Portuguese America. Portugal pushed south from Brazil in the 18th century, starting the fortress of Santa Teresa in 1762 and holding the smaller Fuerte de San Miguel near today's Chuy; the Spanish governor Pedro de Cevallos captured Santa Teresa in 1763. Spain secured the coast by settling Maldonado and, in 1763, San Carlos, whose first settlers included Azorean families.
The hills of Lavalleja are named after Juan Antonio Lavalleja, born near Minas, who led the Thirty-Three Orientals in the 1825 campaign against Brazilian rule. For most of the 19th century the region was cattle country, with Maldonado a small port and garrison and the Atlantic coast almost empty.
Tourism changed that. Punta del Este grew from the early 20th century as a summer retreat for Montevideo and Buenos Aires families, pines were planted to fix its dunes, and Francisco Piria built the spa town of Piriápolis on the bay to the west. The peninsula briefly entered world history in 1961, when the Alliance for Progress charter was signed there, and in 1962, when an inter-American conference in the resort suspended Cuba from the Organization of American States. Artisans and summer visitors came to join the fishing families of the Rocha coast. Since the 1990s building has spread steadily east, and the fight over how much of the Rocha coast should stay wild led to the Cabo Polonio National Park and other protected areas.
