Since the mid-19th century, the community served as a foothold for immigrants to the United States: Irish and Canadians came first, followed by Russian Jews and Italians, then Southeast Asians, and, more recently, an influx from Central and South American countries. The Orient Heights section of East Boston was the first area in Massachusetts to which Italians immigrated in the 1860s and 1870s, and today the heart of the Italian community remains in East Boston. The Madonna Shrine, which is the national headquarters of the Don Orione order, sits on top of the Heights and is a replica of the original religious structure in Rome.
