National Coach Museum (Portuguese: Museu Nacional dos Coches) is one of the best surprises in Belém: royal coaches, ceremonial vehicles, and state carriages fill a huge, light-filled hall near the Tagus. Founded in 1905 and rehoused in the current building in 2015, it turns Portugal's court history into a visit of gilded detail, towering wheels, and one unforgettable showpiece, the Coach of the Oceans.
Start with a direct entry ticket, or choose the audio-guide version if you want the royal backstory without joining a group; it is the easiest way to add context and keep your Belém route flexible.
