on L.B. Brown Avenue (formally Second Avenue). Bartow's discarded natural Christmas trees are piled around a telephone pole for the annual New Year's Eve bonfire, a unique tradition spanning more than seven decades which has sometimes been covered by national media. The Polk County Arts Alliance based in Bartow is designated the official Art Agency by the county commission and is in charge of furthering the performing arts in the county. The Bartow Performing Arts Series sponsors five performances every year. The Imperial Symphony Orchestra is an ensemble of ninety volunteer musicians throughout the county who perform a dozen or so events every year including a concert "under the stars." The city also has a volunteer band, the Bartow Adult Concert Band, which performs several shows a year. On the third Friday of every month, Main Street is blocked off for Friday Fest at 6 p.m. for a night of live music and entertainment, informally known as "Tow Jam" by natives. Historic buildings and landmarks The city's Historic Architecture Review Board is responsible for the preservation, enhancement and promotion of historic buildings, landmarks and districts within the city. Three districts in the city, the Bartow Downtown Commercial District, the Northeast Bartow Residential District, and the South Bartow Residential District have been designated as historic districts. New construction within these districts is regulated by the board and they have the power to veto construction which might alter the character of the neighborhood. While the towering oaks and ever-present azalea bushes which spawned the city's nickname give many of the historic landmarks of the city a distinctive Southern "look and feel", many styles of architecture are represented in Bartow's historic buildings. The South Bartow and Northeast Bartow historic districts are characterized by masonry vernacular and various revival styles, while downtown is dominated by frame vernacular and classical revival styles. Other buildings on the National Register of Historic Places with distinctive architectural styles include the Thompson and Company Cigar Factory built in a Mission Revival Style and the L.B. Brown House built with distinctive Victorian ornamentation. The L.B. Brown House is notable as perhaps the only house still standing in Florida built by a freedman. The Old Polk County Courthouse, Bartow's most recognizable symbol seen on its city seal, was built in 1909 in a neoclassical style. Florida Senator Spessard L. Holland was born in Bartow. His home is located on South Broadway
