On the southwest block near the intersection of South Main Street and West Wooster Street in Bowling Green, a row of commercial buildings became part of the Main Street Historic District in the National Register of Historic Places in 1980: the Union Block of 1877, the Lehmann Building of 1896-97, the Commercial Bank and Savings Company of 1926, and the adjacent Royce Building of 1889. The two-story brick Union Block at 108-112 South Main Street was built by Christoph Lehmann, Dr. Andrew J. Manville, and J. D. Bolles in the Italianate style, with bracketed cornices and arched second-story windows, and housed the Bolles and Manville drug company until 1896, with other commercial and professional tenants as well. Just south at 116 South Main Street, Christoph Lehmann's Classical Revival Lehmann Building reflected influences from the 1893 World's Columbian Exposition in Chicago and featured distinctive cattle heads beside its central second-story arch; Lehmann, born in Germany, emigrated in 1865, traveled with a wandering Italian harpist, settled in Bowling Green in 1871, and built a successful butcher shop after learning the trade in Tiffin, Ohio. At 130 South Main Street, the Commercial Bank and Savings Company was designed in a Classical Revival style with Indiana limestone, a geometric frieze, four round Doric columns, and an entrance ornament that once held a clock; the bank failed before the stock market crash of October 1929, was replaced in 1931 by the Bank of Wood County, and later became Huntington Bank. The nearby Royce Building at 136 South Main Street was built in 1889 by Albert Royce in the Italianate style, with a decorative parapet bearing his name and the construction year, second-story windows with headers and stone sills, and bracketed cornice and trim; its original north wing, which housed the Commercial Bank under Royce's presidency, was demolished in 1926 to make way for the new bank building. The block was also shaped by two prominent local figures: A. J. Manville, M.D. (1834-1902), a physician, farmer, drug store partner, and civic leader who helped secure Bowling Green as the county seat and bring the Wood County Fair there from Perrysburg, and A. E. Royce (1844-1914), a businessman active in agriculture, groceries, property, banking, and oil who served as president of Royce, Smith and Coon and later of the Commercial Banking Company.
