1. Millsboro's Oldest Commercial Structure: The Benjamin Burton Store, a part of the town's history Marker
The structure was built in the Greek Revival style, circa 1840, as a store and storehouse. It was originally situated at the northwest corner of East State and Main Streets. In 1918, it was moved 55 feet west along State Street to its current location to make way for construction of the Millsboro Trust Company. This brick building still stands to this day.
Built by Benjamin Burton, then Millsboro's wealthiest citizens and a prominent businessman and gristmill owner, the store was later purchased, circa 1902, by local pharmacist Ernest C. Blackstone (1872-1950). Mr. Blackstone also served in the 1930s as Delaware State Treasurer. He used the building as a drugstore, with an ice cream parlor in the rear, and as a finance company from 1902 to 1946.
In 1953, the store was occupied by Mr. and Mrs. E. Edward "Ned" Carey, who purchased the building in 1962 and operated Carey's Paint and Frame Shop on the premises until recent years. Mr. Carey was a public-spirited citizens who served Millsboro in many different capacities over the years before his passing in 2004. His wife, Mrs. Beatrice Carey, continued working there until 2016. She died in June 2021, at the age of 101.
The building was placed on The National Register of Historic Places in 2014.
