Palacio Governador

Rich with antiquities, this 60-room hotel, opened in 2016, is like a museum. Built on a Roman site that dates as far back as the first century, there are stone vats and amphorae exhibited throughout. But its life as the home of a governor of Belem yields so much more to admire, including the breathtaking organ pipes in the 18th-century chapel. (Room 116 actually has a window that looks into this chapel.) In keeping with the authentic azulejos guests will find all over the property (but especially by reception), blue dominates the property’s palette: Most rooms have bold, blue floral rugs, a curvy chaise in blue velvet, and navy headboards. The suites are especially stunning thanks to their historic architectural flourishes, including some with vaulted brick ceilings. The outdoor pool is fantastic, but it is adjacent to the highway that separates the hotel from the river; the beautifully tiled indoor pool is just as lovely and is part of what is now one of the very best spas in town. (Rooms, from $150)
