The Louise Arnold Tanger Arboretum's origins trace back to 1956 when local naturalist Louise Arnold Tanger observed the barren grounds surrounding the newly constructed Willson Memorial Building of the Lancaster County Historical Society (now LancasterHistory). She generously offered to plant trees, and with landscape designer Gustaf Malmborg, began transforming the area into an arboretum with over 100 individual species. Mrs. Tanger oversaw the grounds until her passing in 1959, after which her son, Charles Tanger, continued her legacy as the historical society's naturalist until his death in 1991. Following his passing, the "Friends of the Tanger Arboretum" was established, an all-volunteer group dedicated to the care, preservation, and development of this significant community asset.
Enjoy leisurely walks along paved and unpaved pathways, engage in photography, identify diverse plant species using available maps and labels, and relax amidst the tranquil environment. Check LancasterHistory's website for seasonal events and educational programs.
