Sebastião Rabelo de Oliveira Bridge

It was built as a modest inn and restaurant of wood construction, dating from the heyday of the rubber plantation industry in the late nineteenth to early twentieth centuries. The hotel was constructed in a mix of European architectural styles, with allowances for the local climate. After the original structure was destroyed by fire, the mayor of Belém and the governor of Pará provided funding for its reconstruction.

The Capelinha was constructed by Guilherme Augusto de Miranda Filho in fulfillment of a promise he made to God while ill on the island, in exchange for the return of his health. The chapel was dedicated on December 17, 1909, by the acting archbishop of Belém. On the second Sunday in December, the chapel holds a special observation for the patron saint of the people of Mosqueiro.

190 hectares (1.9 km²) of the island have been set aside as a municipal park by the city of Belém, which is seeking to promote ecotourism. The park includes 3 km (1.9 mi) of trails.
