Merchants Smith, Brown and Company built an early department store beginning in 1890. The Northwestern Academy was razed in 1894 and the Towers School erected (which became the city's high school). Merchants National Bank built a building in 1894 which later became the Community Bank. Clarksburg's oldest bank, the Empire National Bank, built a seven-story headquarters in 1907. Other significant buildings include the Goff Building (1911), Municipal Building (1888), the Waldo Hotel (1901–1904), Robinson Grand (1912, 1940), Harrison County Courthouse (1931-1932), U.S. Post Office (1932), Masonic Temple (1911–1914), First United Presbyterian Church (1894), and First Methodist Church (1909, 1956).
