The first documentary record of Olari dates back to 1746, while Sintea Mică was first mentioned in 1467.

Being situated on a flat zone, the commune is lacking in attractive spectacles.

Nevertheless, through trimming up the springs of thermal and medicinal waters, it could become a well-attended touristic place.
