Originally built in 1325 as a customs house and residence for visiting royal officials, a mint was added in the 16th century. Henry the Navigator was born here in 1677 and it remained a customs house until the 19th century, when a new larger building was constructed on the riverside.

There is a small but interesting museum. The building stands on the ruins of the medieval customs and an even more ancient ancient Roman residence.

It is located between the Ribeira and the Praca do Dom Infante.
