Why You'll Love This Place

A Here Comes The Guide Wedding Venue Review
  • Named one of the Seven Wonders of Illinois, this sprawling park surrounding the picturesque Sangamon River encompasses 1,500 well-preserved acres with a meadow, lowland and upland forests, and a prairie.
  • You have a choice of 14 exquisite Formal Gardens for a beautiful outdoor ceremony. Designed by Robert Allerton, they include the sleekly minimalist Sunken Garden, the colorful Annual Flower & Butterfly Garden, and the striking Avenue of the Chinese Musicians.
  • The 100-year-old Allerton Mansion offers a refined indoor reception setting. Its elegant Georgian-style rooms have a timeless beauty, and the on-site catering provides everything from butler-passed hors d’oeuvres and entrée stations to dessert displays.
