The old Customs Office

 walking from the Ribeira in Porto  towards "Palácio da Bolsa" (Stock Exchange House), you quickly pass by the old customs house.

It is one of the oldest buildings in Porto, the birth place of Infante D Henrique (Henry the heir to the throne)

The building was built in 1325 as a warehouse  but it was considered the place to tax all arriving goods.

1990 were due to renovation work and excavations, evidence of Roman occupation have been found, among other Roman mosaics.

The customs office has to work until 19th century until it was finally replaced by the "new Customs office."
