The Brazilian port town of Paraty developed first as a port to ship gold during Brazil’s 18th century gold rush and thence subsequently coffee and sugar until the building of a railway at the end of the 19th century allowed growers to transport directly to Rio de Janeiro. The town then became isolated until connected by a paved road during the 1970s. Today it is an architectural gem which became a UNESCO world heritage site in 2004. Rua de Praia is one of its preserved cobbled streets.
