The Casa do Infante (House of the Prince), or alternately as the Alfândega Velha (Old Customshouse) is a historical house in Porto. The house was originally built in the 14th century as customs and mint, although its present condition derives mostly from a remodeling carried out in the 17th century. Its name derived from an oral tradition that suggested the house was the birthplace of Prince Henry the Navigator in 1394.
