In August 2018, I spent a couple of days in São Luís, the capital of the Brazilian state of Maranhão. São Luis was settled by France in the early 17th century, the only city founded by that country in Brazil, and occupied briefly by the Dutch before being conquered by the Portuguese in the middle of the 17th-century. The late 17th-century core of São Luís, where many of the buildings are covered with traditional azulejos tilework, is the best preserved Portuguese colonial city in Latin America, so no surprise it was added to the list of World Heritage Sites.
