Oliveira do Bairro (Portuguese for: olive tree of the neighbourhood) is a municipality and town in Portugal with 6385 inhabitants.  Celtiberians settled in the district, now the municipality of Mamarrosa. Finds prove the presence of the Romans in the present-day municipalities of Palhaça and Bustos. The present-day town is first documented in a deed of donation from 922, under the name Ulveira. Oliveira do Bairro was granted its first town charter in 1514 by King Manuel I, who elevated the town to a vila (small town). In 1836 it became an independent district (concelho). In 2003, Oliveira do Bairro was elevated to a city (cidade).
