The parish of São Caetano is also known as Prainha do Sul or Galeão, in honour of Garcia Gonçalves Madruga who built here in the 16th century, as payment to King John III, for his debits.

At the same time a ship wrecked laden with wheat and timber, which ended-up being used for the construction of the parochial temple.

The local populous attributed these to acts of God and a miracle, as it occurred at a timely point the parish's life.

It is a geologically accented region marked by evidence of lava fields and landslides extending from the coast to the summit of Ponta do Pico.

The most significant built-up patrimony in the parish include the parochial church, the hermitage of Santa Margarida, the tidal pools, Casa do Povo and some older adegas (or wine-cellars).
