Today's church of "San Rocco al cimitero" in Segrate, formerly dedicated to San Nicolò (from Bari), was commonly known as "San Nicola al lazzaretto"; in the surrounding spaces, in fact, plague patients were welcomed. During the last restorations (1984-86) traces of an old floor and the base of an altar were found next to the perimeter wall of the apse, which suggest the existence of a primitive aedicule built perhaps on the occasion of the Manzonian plague of 1630. On 4 November 1696, the provost Braga instituted a benefice for him with the obligation to celebrate a festive mass and on the anniversaries of St. Anthony, St. Francis and St. Nicholas. Between 1717 and 1723 the provost Cagnola had it enlarged with the addition of the nave to the ancient oratory which became the current apse. In the map of the Teresian land registry (1723), in fact, the church is outlined with the current perimeter, it is still dedicated to the bishop of Bari and the field to the northwest, now part of the cemetery, is called "li campi de Lazareto". It is in the documents of the renovation of those years that we learn of the existence of a second altar dedicated to San Rocco leaning against one of the side walls of the oratory.
