Rosemount offers guided tours and historical / educational programs to the public. The organization also hosts several events and activities throughout the year. The 85% intact original collection makes Rosemount a "must see" when traveling through southeastern Colorado. John Thatcher and his brother Mahlon were instrumental in the building and growing of Pueblo and their contributions were far-reaching. Our goal is to share their story and to preserve the mansion and property for the enjoyment and education of future generations.
