Your journey begins in Praça Coronel Horácio de Matos, the beating heart of Lençóis since its founding in 1844. This central square, named after Colonel Horácio de Matos, a local political figure of the 19th century, was the gathering point for garimpeiros. Surrounded by typical Bahian sertão colonial buildings, it still echoes with animated discussions about the latest finds. Here, miners exchanged information and hopes before venturing into the Chapada Diamantina. This square is the ideal starting point to understand the effervescence that marked the history of Lençóis and Northeast Brazil.
Continue to the Mercado Cultural, a building that was once a covered market built in the 1850s. This place is inseparable from the trade of locally extracted diamonds. It was here that garimpeiros came to sell their precious stones, transforming the market into a true nerve center of the diamond economy in the 19th century. Converted into a cultural space in 1980, it preserves its typical stone architecture of diamond centers, allowing you to visualize the intensity of the transactions that took place there. The Mercado Cultural is an essential witness to Lençóis' heritage.
The Igreja Nosso Senhor dos Passos, built in 1860, is your next stop. This Catholic church, dedicated to the patron saint of travelers, was funded by prosperous Lençóis miners. Its neoclassical architecture and 20-meter-long nave testify to the wealth generated by diamonds. The garimpeiro community celebrated masses and religious festivals here, strengthening social bonds during the diamond cycle, which lasted from 1844 to 1940. This church is a symbol of the faith and prosperity that shaped Lençóis.
Casa de Afrânio Peixoto, a colonial house dating from 1870, was the residence of the writer Afrânio Peixoto (1876-1947), a native of Lençóis. Now a museum, it houses artifacts from diamond garimpo, including tools and stone samples. Peixoto wrote works inspired by local mining history here in the 1910s, offering a literary perspective on this intense period. This site, which would later become the Casa de Cultura Afrânio Peixoto, is a bridge between the factual history and the cultural memory of Lençóis.
Your exploration concludes at Mirante da Lençóis, a viewpoint developed in the 1920s, 1.5 km from the center. From here, you admire a panoramic view of the valley and the old diamond extraction areas. This rocky promontory was a strategic observation point for garimpeiro expeditions in the 19th century. By contemplating this landscape, you grasp the scale of the miners' work and the legacy of the UNESCO diamond heritage of Chapada Diamantina. This is the culmination of your interactive visit to Lençóis, a testament to the history of Bahia and Northeast Brazil.
