Mulberry, Florida’s original railroad depot became a local history museum in 1986 devoted to the phosphate mining industry that shaped the community. Its exhibits combine industrial history with fossils and community memorabilia, linking the business of phosphate extraction to the landscape and daily life that grew around it. The depot setting underscores how rail transport was central to moving and trading phosphate. In 2013, the collection gained a recently discovered phosphate locomotive from the 1880s, connecting the town’s railroad heritage with the industry’s early years. Together, these features preserve a compact record of the mining economy that defined Mulberry’s development.
