[2] Achadinha is one of the oldest localities in the municipality of Nordeste, referred to by Gaspar Frutuoso in his chronicle, Saudades da Terra.

During this century, a small temple was constructed to the invocation of Nossa Senhora do Rosário (Our Lady of the Rosary), which was served by its first vicar Pêro Vieira.

Achadinha, during the 17th century, was still little more than a small settlement, distant and isolated from the great centres, such as Vila Franca do Campo and Ponta Delgada.

Many of the inhabitants walked barefoot, wearing shabby rags, made of linen, in a region that was distant from any other centre.

The parish diversified its activities, but deviated little from its agriculture and animal husbandry, with the production of milk and beef cattle.
