Beacon Hill is a prime time period drama series which aired on CBS in 1975. Set after World War I in Boston's Beacon Hill area, the show was conceived as an Americanized version of the popular British series Upstairs, Downstairs (1971–1975) and focused on the wealthy Irish-American Lassiter family and their Irish immigrant servants, who reside together on Louisburg Square. The show was produced by Jacqueline Babbin and Beryl Vertue, the former literary agent of Upstairs, Downstairs co-creator Jean Marsh.
