Tremont Square District included the 1847 brick Greek Revival Third Orthodox Congregational Church at the north corner of Main and East Pearl on the former site of the American House Tavern; according to the Nashua Telegraph, it was designed without the "questionable ornament" of a steeple. The area also included the Currier Building, Dunbarton Building, Parkinson Building, the 1891 Masonic Temple Building, and, south of the temple, Nashua's first modern high school, designed by W.D. Clark in 1853. In 1910 the high school was torn down except for its north and south walls, which became part of the Colonial Theater, designed by Duane F. Holt to accommodate 1194 people, and it operated until 1954. At the north corner of Main and West Pearl Street stood the three-story Pearl Street House, later renamed the Tremont House, built between 1847 and 1848 for officials of the Nashua Manufacturing Company. After a fire in the Tremont stables in 1873, a balcony replaced the portico. It later hosted Rutherford Hayes, William Taft, and Theodore Roosevel during their visits. By 1916 the stable contents were auctioned and the property was sold to the Second National Bank. After another fire in the stables in 1921, the Tremont Hotel was torn down in 1922. The Second National Bank erected a Classical Revival limestone and granite building in 1924, and in its first six hours open, 10,000 people came to survey its interior.
