This paper aims to present the results of a comprehensive study conducted on the northern and western facades of the church of San Nicolò dei Mendicoli in Venice. Historically situated on the outskirts of the city, this building has recently garnered renewed scientific attention. The investigation employed a method developed in previous scholarly research, which combines the stratigraphic analysis of the elevations with mensiochronology, assessment of masonry material and constructive attributes, examination of indirect sources, and comparative analysis with previously published case studies. Consequently, five construction phases dating from the 12th-13th centuries to the 20th century have been identified. The research has achieved a double result: not only was it possible to link each architectural transformation to the church's community history, but it also could become a useful case study for the analysis of other Venetian buildings.
