The Main Street program is supported by the City of Haines City and cooperating state agencies as an ongoing project that has revitalized and invigorated the central core area known as Historic Downtown Haines City. It has included many of the red brick and art-deco buildings of the early 20th Century. Among these is the eight-story Polk Hotel, built in 1926 by Ralph Polk to help house the workers in his grapefruit canning plant. It later became known as the Palmcrest, and in 1997 was purchased by Landmark Baptist Church for use as Landmark Baptist College. It has been refurbished entirely through the lower floors, and work continues on the upper levels.
Visitors are welcome on a pre-arranged basis.
In the downtown core center, many of the buildings now house specialty gift shops, antique collections, beauty salons, medical offices, and service businesses. A number of them have been assisted in restoration by incentive grants and a CRA Loan Pool Program. A Fall Festival attracts several thousand people, and the weekly Wednesday farmers market is a popular feature.
