In Venice, where the historical urban fabric is peculiarly intricate and compact, the absence of a straight and wide street for promenading was obviated in the 16th and 17th centuries by laying straight strips of Istrian stone across what had previously been dirt squares, such as Campo Santo Stefano, Campo San Polo, and Campo Santa Maria Formosa.
The word liston, the traditional Venetian term for a public promenade, probably came from those strips or from the lines of white marble laid in the flags of St Mark’s Square in 1406 to demarcate the Saturday market stalls and that came to function as a reference point for corso-like paths.
The promenade was performed up and down the piazza along the east-west axis. Opening up in front of the centres of both political and religious power—the Doge’s Palace and, beside it, the basilica—the public space of St Mark’s Square became the main site for urban displays and parades from medieval times onwards. Ascension Day and Carnival Thursday began to be celebrated here in the 12th century and, before the current 18th-century pavement was laid, the square hosted horse races, jousts and tournaments.
