It opened in April 1918 and was designed by architect W. H. Weeks, and it now serves as Colusa City Hall.","why_significant":"The nomination calls it one of Central California's last intact examples of pre-World War I Gothic Revival school design. It is also one of the area's first significant poured-in-place reinforced concrete multi-level buildings. For its time it was innovative in fire safety, circulation, heating and ventilation, and it was hailed at its dedication as perhaps the finest school building in the state.","narrative":"Colusa Grammar School is a two-story red brick building at 425 Webster Street, designed in the Tudor Gothic Revival style by San Francisco architect W. H. Weeks and built by J. S. Hannah. It opened on April 11, 1918, after local voters approved bond issues to fund what newspapers reported as a $100,000 building. Its textured brick walls rest on a cast stone base and are trimmed with terra cotta ornament, tracery and balconies. Inside, a 650-seat auditorium has ornate plasterwork. The design stressed safety and comfort, with ramps instead of stairs, concrete-encased corridors, outward-opening doors, forced-air heating and shaded hopper windows. It served as a school for 58 years, until 1976. The City of Colusa then acquired it for use as city hall, and it was designated a local landmark in 1977. A later classroom wing was considered an intrusion and was excluded from the nominated property.","period_of_significance":"1918","architect_builder":"W. H. Weeks, architect; J. S.
