The history of Lençóis, in Bahia, begins with diamond mining. The origins of the town are linked to the discoveries made in 1844 in Mucugê and to the rush of prospectors who, the following year, climbed the mountains and founded the settlement. The Diamond Cycle brought wealth to the town, and the heritage that remains from this period – the architectural and landscape complex listed by IPHAN in 1973 – is now the town’s main tourist attraction. Lençóis is also the main gateway to the Chapada Diamantina. Updated in October 2026.

The origins of Lençóis: from the gold mine in Mucugê to the village

The first diamonds in the region were found in 1844, on the banks of the River Cumbuca, in Mucugê. The following year, the prospectors made their way up into the mountains and founded the settlement that would become Lençóis. The news attracted adventurers from various parts of the country, and settlement spread around the mining areas. To understand the regional context, see also the history of the settlement of the Chapada Diamantina and the history of mining in the Chapada.

The best-known explanation for the name is that the prospectors’ white tents, seen from a distance, resembled sheets hung out to dry across the valley. There is another version, cited in tourist guides, which links the name to the river water that forms foam as it flows over the rocks during floods. In 1856, the region was separated from Santa Isabel do Paraguaçu and became the town of Lençóis, and in 1864 it was granted city status.

The Diamond Cycle in Lençóis (1845 to 1871)

According to IPHAN, between 1845 and 1871 Lençóis was the world’s largest producer of diamonds and the third most important city in Bahia. The city became a trading hub: it exported the mineral to Europe and imported luxury goods. To facilitate this trade, France established a vice-consulate there. It was during this period that the first townhouses and more elaborate buildings began to appear. This period had lasting effects:

• Population growth: the arrival of prospectors, traders and families in search of fortune.
• Economic development: the expansion of trade, public works and higher-standard housing.
• Political influence: the mine owners formed an elite, from which Colonel Horácio de Matos emerged.
• Culture and identity: architecture and traditions bear the hallmarks of this period.
• Decline and reinvention: as the ore deposits were exhausted and competition from South African mines intensified, the town saw its population decline and eventually reinvented itself through tourism.

The mines discovered in South Africa from 1865 onwards shifted the international market’s focus to African diamonds, and by around 1871 the heyday of Lençóis had come to an end. Prospecting continued on a smaller scale, notably for the carbonado, the black diamond, and the Chapada became known for the ‘Carbonado do Sérgio’, found by a prospector almost 130 years ago and sold in fragments. To understand the stone, see the characteristics and the 4 Cs of a diamond.

Colonel Horácio de Matos and the colonels’ conflicts

Colonel Horácio de Matos (c. 1882–1931), who succeeded his uncle Clementino Matos as head of the mining districts, was the most influential political figure in the Chapada, wielding considerable influence even with the federal government. He defeated local rivals, led a march towards Salvador in 1920 (the Sertaneja Revolt), which ended with the so-called Lençóis Agreement, and in 1926, at the request of the federal government, fought against the Prestes Column. He was arrested in December 1930 and assassinated in Salvador in May 1931. Today, the city’s main square is named after him.

Heritage and listed status: the historic quarter of Lençóis

The architectural and landscape complex of Lençóis was listed by IPHAN in 1973 (December 1973, file 847-T-1971, according to a report from 2026) and is one of the ten complexes protected by the agency in Bahia. The protected area comprises around 570 properties, mostly 19th-century houses and townhouses. The town is situated in the central-western region of the state, in a natural amphitheatre on the eastern slope of the Serra do Sincorá, and IPHAN classifies it as part of the Chapada Diamantina National Park. See also other towns listed as historic heritage sites in Bahia.

Characteristics of heritage

The collection comprises houses and two-storey dwellings from the second half of the 19th century, built of adobe or stone, and wooden structures with hand-rammed earth walls. The bright colours on the walls and window frames are a hallmark of the buildings. Secular architecture takes precedence over religious architecture, and there is no single monument that dominates the ensemble. To learn about the region’s architectural style, read about the architectural style of the Chapada Diamantina.

The development of the settlement and its colonial street layout

The settlement grew out of two centres,  Serrano and São Félix, which developed alongside the mining areas and later merged into a single urban area. Serrano was situated on high ground next to a set of rapids and, over time, shifted towards what is now Praça Horácio de Matos. Construction of the chapel of Nossa Senhora da Conceição began in 1851 and it was later replaced by the parish church.

The bridge dating from 1860 and the grand townhouses

The bridge over the River Lençóis was built in 1860, making use of the surplus labour caused by the great drought of 1859 to 1862. The large townhouses in the former Praça do Mercado – now Praça Horácio de Matos – date from that period, including five listed residences. The Casa do Conselho was demolished in the 1940s to make way for the Post and Telegraph Office.

Unplanned development and road surfacing

As with other mining settlements, Lençóis grew in a haphazard manner, with irregular streets that follow the contours of the land, small squares and open spaces. In some places, the road surface is the local rock itself, and there are streets paved with irregular stones that form patterns. New streets, whether created spontaneously or approved by IPHAN, follow the colonial grid pattern.

Listed monuments and public spaces

According to IPHAN, the following are among the protected assets:

• Horácio de Matos Square (the most important public space)
• Municipal Public Market
• Bridge over the River Lençóis
• Town Hall
• IPHAN Technical Office premises
• Former Health Centre
• Arena Theatre
• Church of Our Lady of the Rosary
• Church of Our Lord of the Steps
• Afrânio Peixoto Cultural Centre and Amphitheatre
• Public Library
• Public Archives

Six buildings to visit in Lençóis

These six buildings help to tell the story of the town. For a complete itinerary, see things to do in Lençóis.

1. IPHAN headquarters in Lençóis
2. UEFS Advanced Campus Building
3. Former French Vice-Consulate
4. Cultural Market
5. Bridge over the River Lençóis
6. Church of Our Lady of the Rosary

1. IPHAN’s headquarters in Lençóis

For many years, the building housed the Town Hall (on the ground floor) and the public prison (in the basement), and later the City Council. Tourist guides describe it as a building dating from the 1860s, now occupied by the IPHAN office.

2. UEFS Advanced Campus Building

Built in the Neo-Gothic style, the two-storey house stands on the corner of Praça Horácio de Matos. The Neo-Gothic style was widely used in the towns of the Chapada region in the late 19th century.

3. Former French Vice-Consulate

The building is situated in the row of houses on Rua Sete de Setembro and is linked to the diamond trade with Europe. The French vice-consulate was established in Lençóis to facilitate this trade, and today the property serves as both a residence and a business premises.

4. Cultural Market

The Cultural Market is a central hub of the city’s cultural life and hosts events from the Lençóis Festival, such as round-table discussions on popular culture and the environment. The façade blends into the landscape thanks to its proximity to the River Lençóis. The film Diamante Bruto (1977), directed by Orlando Senna, is set in Lençóis and depicts the town following the decline of the mines.

5. Bridge over the River Lençóis

The bridge, built in 1860, is the only link between the two sides of the city divided by the river. In July 2026, a local resident reported signs of wear and tear at the base of one of the piers, and IPHAN asked the local council for an updated structural stability report. Any work on the bridge must be approved in advance by IPHAN.

6. Church of Our Lady of the Rosary

Described in tourist guides as the largest church in the Bahian hinterland, it is a centrepiece of the city’s religious heritage. The date of construction varies depending on the source, and IPHAN does not specify the year, so it is worth checking the information before quoting it.

Culture and festivals

Lençóis’s architecture preserves the memory of a time of prosperity, and its folk traditions are a highlight, particularly the June festivals, featuring forró, quadrilha and cavalhadas. The Senhor dos Passos festival is also part of the calendar.

The Lençóis Festival, which is sometimes referred to as the Winter Festival in some promotional material, held its 27th edition in 2026, from 4 to 6 September. The event was free to attend and took place in public spaces such as Horácio de Matos Square, the Cultural Market and the bandstand. The theme was ‘Sing, Plant and Protect’, and the organisers reported an attendance of around 30,000 people. Shops, restaurants and bars are concentrated in the streets near the main square.

Lençóis today: tourism and new accolades

In July 2026, the Ministry of Tourism announced that Lençóis was one of seven Brazilian cities nominated for the UN World Tourism Organisation’s ‘Best Tourist Towns in the World’ award, and the only one in the North-East.

The result was due to be announced in December, in Buenos Aires. As well as its historical heritage, the city serves as a base for the Cachoeira da Fumaça, the Pantanal dos Marimbus and other attractions.
