"Brecha da Arrábida": an update summary including

The Arrábida Breccia is a carbonate conglomeratic breccia occurring only in the chain with the same name, located in the central-occidental part of Portugal, close to the Setúbal city. It has been used from the last 2.000 years, since the Roman occupation of the Iberian Peninsula, until the exploration was completely stopped after the creation of the Natural Park of Arrábida in 1976.
