By the mid 20th Century, Thomasville's built environment was under attack. Many significant historic structures were facing demolition and redevelopment. Crisis hit a fever pitch when Thomasville's Italiante library was razed, and numerous other important landmarks were threatened.
In 1964, a small group of concerned citizens banded together to encourage the preservation of Thomasville’s unique environment. Landmarks was formally incorporated in 1966 and continues to lead the community in preservation of character.
