For many in Cambridge – a college town – late summer heralds the return of students to the city. Families, teachers and students seek a last gasp of freedom before a return to the fall routine, and those who thrive on the warm temperatures and long days of summer coming slowly to terms with the reappearance of all things pumpkin spice.

Late summer is also the time of street festivals, many of which celebrate the history and culture of Cambridge’s wide variety of communities. On Sept. 6-8, one such festival celebrates its 99th year – nearly a century of bringing Cantabrigians of all ethnicities together to eat, drink and honor two of the Italian community’s important saints.
