Remanso was originally inhabited by
indigenous people of the Acoroase ethnic group. Refugees of armed conflicts in the nearby municipality of
Pilão Arcado arrived in the 19th century. The area was fertile and due to its location on the Old Frank, provided a good
site for cattle ranching and fishing. The area quickly attracted new residents who founded the town of Ville de Your Miss of Remanso of Pilão Arcado in 1857. This became an independent municipality on August 9, 1900 under the name of Remanso.
Relocation Under Brazilian Federal Law n°. 10/77 of January 28, 1977 the municipality was relocated 4.3 miles from its original location in 1974 for the construction of the Sobradinho Dam. The new location, referred to as New Remanso, was constructed by
Companhia Hidro Elétrica do São Francisco (São Francisco Hydroelectric Company). The municipality lost a quarter of its territory with the construction of the dam and the old city is now submerged under the Sobradinho Reservoir. ==Festivals==
