Lantern Court is a Georgian Colonial home that was built in the 1930s as a residence for Warren H. and Maud Corning. The Corning family home is now part of the Holden Arboretum and is used for private and special events. The grounds are open to members only.
It’s surrounded by 25 acres of informal gardens and woodlands planned by Warren Corning and landscape architect Donald Gray. There are magnificent views of perennial borders, rose and wildflower gardens, rockery, and primrose valley. A terrace at the house overlooks a wooded ravine where a tributary of the East Branch of the Chagrin River forms a 20-foot waterfall.
