The city of Venice preserves nowadays not only important monumental buildings, but a great part of the historical tissue of its common residential buildings. This tissue has been traditionally divided in six quarters or sestieri (Castello, Cannaregio, Dorsoduro, San Marco, San Polo y Santa Croce) that have a good number of noble palaces among a greater part of traditional and vernacular residential buildings. Frequently, these residential buildings group themselves around a patio, called corte, a very unique and interesting architectural space. The corte, normally served by one at most two not confronted streets, constitutes a very peculiar and elaborated element of the traditional Venetian architecture. It is a semi-public space where the surrounding buildings open their windows that represents the filter between the public space of the streets and squares of the city and the private world of the private dwellings.
