Three Pines

Three Pines is a historic mansion and event venue in Petersburg, Illinois, offering a distinctive setting for intimate weddings, private gatherings and overnight stays. The property combines the character of a nineteenth-century home with a barn and 3.5 acres of grounds, giving organisers a choice of indoor and outdoor spaces for their event.

Couples can plan a ceremony and reception on site, with options including the garden, the rustic barn and the mansion’s elegant rooms. The venue is particularly suited to smaller weddings, while larger gatherings may be possible with additional arrangements such as a hired tent and portable toilets. Tables and chairs are available for use, and organisers can choose their own caterer, bartender, photographer, entertainment and planner. The team can also suggest local suppliers.

Three Pines welcomes more than weddings. Its spaces can be used for family reunions, retreats, showers, engagement parties, wine tastings, cooking classes and other private events. Depending on the gathering, organisers may be able to book the barn, grounds, library, dining room or living rooms rather than the entire property. The venue team works with organisers to discuss the suitable space and event details.

Overnight accommodation is an important part of the experience. The mansion has several guest rooms and suites, shared living areas, a kitchen and outdoor gathering spots. Groups can also arrange to rent the whole house, making it a practical option for wedding parties, family gatherings and retreats where guests want to stay together. With its heritage architecture, flexible event spaces and lodging on site, Three Pines offers organisers a welcoming base for a gathering in the heart of Petersburg.
