The place

About Allerton Park & Retreat Center

Allerton Park & Retreat Center brings art, nature, and history together on more than 1,500 acres southwest of Monticello. Visitors can explore 14 formal gardens created by Robert Allerton between 1899 and 1946, discover more than 100 sculptures and garden ornaments, and hike 14 miles across seven trails through forest, prairie, and Sangamon River landscapes.

The McCraw Family Visitor Center provides maps, displays, and restrooms daily. The Mansion's first floor may be open for self-guided viewing when it is not reserved; private events and maintenance can close indoor or outdoor areas without much notice, so the gardens and visitor center are the more dependable walk-in anchors.

Robert Allerton gave his house, grounds, and 3,600 additional acres of farmland to the University of Illinois in 1946 for education, research, conservation, landscape gardening, and public-park use. Community advocacy later protected the park from a proposed dam and supported restoration, programming, and accessibility improvements.

The park is free and generally open from 8 a.m. to sunset. Because the century-old property is not fully accessible, Allerton publishes a suggested accessible route, lends one wheelchair first come, first served, and offers reservable power chairs with at least 48 hours' notice.
