Culture
Trenton is most famous for its collection of rare antique porcelain veilleuses, donated by the late Dr. Frederick C. Freed in 1955. The teapots are unique because the candle's glow illuminates the pot's exterior, thus serving as a night light. None of the 525 teapots in this collection are alike, and some are designed as palaces or people in unique still-life castings. The town celebrates its collection with an annual "Teapot Festival" held each spring since 1981. Trenton is also known for its unusual speed limit of, established by the city in the 1950s and posted by signs throughout the town. Nite Lite Theatre of Gibson County is a non-profit community theatre project based in Trenton, and established in 1980 with the intent of bringing theatrical presentations to Gibson and the surrounding counties. All work, with the exception of some production staff, is done on a volunteer basis. With most performances at Peabody High School, the history of Nite Lite Theatre includes performances of The Man Who Came to Dinner, The Sound of Music, Dearly Departed, and You Can't Take It with You.
