The ballroom was also used as a government meeting hall. John McLoughlin and other officials of the Hudson's Bay Company were entertained there by Americans who had only recently declared their sovereignty. It is believed that the Rose Farm is the only building in which both the Provisional and Territorial Legislatures met. When Jospeh Lane, the first federally appointed Territorial Governor, took office in 1849, he delivered his first official address from the balcony to a crowd of 300 people assembled on the lawn below. The Rose Farm Museum is open on Sundays from 1 to 4 PM from March through November.
Group tours are available by appointment for groups of eight or more.
