The house that this gorgeous Charleston doorway is in dates to Colonial times, but the door itself is a more recent addition. Located on Rainbow Row, as with most buildings on this stretch of East Bay Street, the first floor was originally used commercially (in this case as a counting house and then as a grain and feed store). In 1941, when Susan Pringle Frost — the founder of the modern day preservation movement in Charleston — restored the building she replaced the existing storefront with this door.
