Urban islands are an important part of the history of the city of Porto, having been a very common type of housing in the city from the 19th century onwards. They were composed of semi-detached houses, built in the long patio of the bourgeois houses. They were small houses, usually with a door and a window facing the access corridor through which all the other houses that made up the island were distributed.
