St Mary of Carmen Society Festival | Newton MA News and Politics BlogThe 80th annual St. Mary of Carmen Society Festival opens this Wednesday, July 15 at 6 p.m. at Pellegrini Park in Nonantum. If you’ve never been, you’re missing something really special. There’s so much to see and do: amusement park rides, food, music, entertainment, politicians, regular people, procession, flight of the angel, author of Legendary Locals of Newton selling and signing her book Wednesday night (!). But best of all, Nonantum is transformed into Italy for five nights.
