Winn's home was the site of the first Gwinnett election and court sessions in 1819. The Winn House grounds are home to the Walnut Grove School, a one-room school that has been restored to its 1870's appearance and the 1820 Lawrenceville Jail, built of logs. The two-story, plantation style home has been restored to 19th century specifications and offers an authentic look at the past.

The home is open for tours from March to September on the third Saturday of the month from noon to 4:00 p.m. The Winn Fair is held on the first weekend of October during which the house and all of the out buildings are open and attended by many volunteers and reenactors.
