Hi !

This house named Infante because is perfect credibly that Infante D.Henrique, know as the Navigator, was born here. The House use from the Middle Age was as Custom House or Home House. Incredibly when a restoration was made the archeologics discover an Roman house with mosaic floor ! The escavations continues and others artefacts as coins, ceramics and walls appears. So the house instead of beeing used for two eras, Middle Age and XVII and XVIII centurys, was used since the Roman Period, when Oporto was Portu.
