Coat of Arms House or Casa do Brasão is a 17th-century mansion located on the main street of Tabuaço. The house still preserves details of the original building, including a stone coat of arms, a wooden staircase and decorated ceilings. It is an excellent example of Portuguese mannerism. Today, Casa do Brasão, is transformed into local accommodation, in the Douro wine region, the Alto Douro Vinhateiro.
