After the large Revere family left the house, it was used as a shop and a tenement for 19th-century Irish, Jewish and Italian immigrants to Boston. In 1902, Revereâs great-grandson purchased the building to ensure its longevity. By 1908 the Paul Revere House had opened as one of Americaâs first historic house museums.
