Arbor Lodge State Historical Park in Nebraska City, Nebraska, is the original estate of J. Sterling Morton. It was on this property in 1872 that the idea for a tree-planting holiday was first conceived. It is estimated that nearly one million trees were planted in Nebraska on the first Arbor Day.

The showpiece of this 72-acre park is the historic mansion, with its 52 rooms and countless historic artifacts belonging to the Morton Family. The park also includes an arboretum, Italian terraced garden, log cabin, carriage house, walking trails, more than 200 varieties of lilacs and a charming whispering bench.

The park grounds are open year-round; a park permit is not required to enter. The mansion is open to explore and for special events under the direction of the Arbor Day Foundation. Arbor Lodge State Historical Park is owned by the Nebraska Game & Parks Commission.
