Colton Hall, Government building in Monterey, California, US

Colton Hall is a government building in Monterey featuring Greek Revival architecture with white walls made from local shale and a columned portico facing Pacific Street. The structure has two floors, with the lower level presenting local history exhibits while the upper floor recreates the spaces where the constitutional convention took place.

Walter Colton, Monterey's first American alcalde, built Colton Hall between 1847 and 1849, funding it with taxes on liquor and gambling, city lot sales and convict labour. The 48 delegates from ten districts met on the upper floor from 1 September to 15 October 1849 and wrote California's first state constitution, ratified on 13 October. The Native Sons of the Golden West secured a legislative appropriation for repairs in 1903, and the building became a California Historical Landmark in 1934.

The upper floor displays artifacts and documents from the 1849 Constitutional Convention, showing how California's founders debated and shaped the state's early laws. You can see the actual room where these discussions took place, giving a sense of the conversations that shaped the region.

The building is centrally located in Monterey between Jefferson and Madison Streets and is easy to find within walking distance of downtown attractions. Both floors are accessible to explore, and you can move through at your own pace to focus on areas that interest you most.

The building was partly funded through local fines and tax revenue, making it a remarkable community project under Walter Colton's leadership. When completed in 1849, it stood as California's largest public building at that time.
