Join in this annual event as our four Great Road Heritage Campus sites along with other participating historic sites along Great Road open their doors for a peek inside.  The free event provides the opportunity to get a taste of the rich history we have in the Town of Lincoln and a good reason to return for a full visit at another time.  The sites include 17th, 18th, and 19th century architecture and each will have their own special exhibits and stories to share. Many are only opened a few times a year.
