In August 2018, I visited Macapá, the capital of the Brazilian state of Amapá, the only pair not covered by Lonely Planet, so I wasn’t surprised that there weren’t any other tourists.  One of the benefits of a 40-minute flight that departed from Belem at 4:10 am was that I arrived early enough on the northern bank of the Amazon to watch the sunrise over the world’s largest river.  Macapá’s only noteworthy site is São José Fortress, built in 1764 by the Portuguese to guard the mouth of the Amazon.  The fort basically sits on the equator and is the northernmost fort in the tentative site ensemble.
