Dr. Frank Ross built this brick building in 1885 after destructive fires destroyed the two previous wooden buildings on the site. Originally only two stories tall, it first housed Dr. Ross’s office and pharmacy, and over the years it contained various businesses including a post office, barber shop, printing establishment, drug store with soda counter, and hardware store. Dr. Ross lived directly across Grove Street in the house now known as the Kennebunk Inn, which was built as a private home circa 1799 by Benjamin Smith and was later purchased and converted into a tavern in 1928.
