The Osborne Homestead Museum celebrates the life of Frances Osborne Kellogg, an accomplished businesswoman and conservationist who was dedicated to preserving land for future generations.
Adjacent to the rolling hills and open meadows of Osbornedale State Park, Osborne Homestead Museum encompasses the house and grounds of the former Frances Osborne Kellogg Estate. Originally constructed in the mid-1800’s, the house was enlarged and completely remodeled in the Colonial Revival style during the 1920’s. Listed on the National Register of Historic Places, its restored interior now displays the original contents of the estate, which constitutes a significant collection of antiques and fine arts.
The Museum’s grounds are landscaped with formal flower gardens, ornamental shrubs, and flowering trees, providing visitors with an endless pageant of color from spring through autumn. The Osborne Homestead Museum is a member of the esteemed Connecticut Historic Gardens, a group of fifteen distinctive historic houses dedicated to bringing awareness to the state's unique history and garden designs. The museum is also one of the fourteen sites along the prestigious Connecticut Women's Heritage Trail, a collection of museums and institutions that highlight the role of women in the state's history.
The regular tour season runs from May through October. During the tour, visitors learn about the history of the Osborne family, Frances Osborne Kellogg’s role in local and state history, her impact in agriculture, the arts, the environment, and industrialization, and life in the Naugatuck Valley in the early 1900s.
