Historical site
The Fortaleza de Santa Teresa is an imposing stone fortress located within the Santa Teresa National Park in the Rocha department, close to the border with Brazil. Its construction was initiated by the Portuguese in 1762 to secure their territory, but it was captured shortly after by the Spanish, who continued and expanded its construction. The fortress has an irregular pentagonal shape with five bastions and was built from massive granite, giving it a formidable appearance. Its strategic location allowed control over the then-land route between the Portuguese and Spanish colonies. Throughout history, it changed hands several times and fell into disrepair after the end of the colonial wars. In the 1920s, historian Horacio Arredondo led an ambitious restoration project that returned the fortress to its current splendor. Today, it is one of Uruguay's most visited historical sites, surrounded by the 3,000 hectares of forest, beaches, and gardens of the national park.
