Swan Pond

Designed and installed in 1905 by John Morris, this is an artificial lake created by damming the East Brook, which naturally flows through the Arboretum. The idea may have come from the popular 18th-century landscape design style of the English romantic landscape which often included a classical temple reflected at water’s edge. Files from that time period indicate the Morrises purchased a pair of swans in 1923, for $82.50. Mute Swans mature at four years and usually mate for life. Females lay an average of six eggs in the spring at two-day intervals. Cygnets, or baby swans, hatch after 35 days and can swim after one day. Adults share rearing duties and are extremely protective – they may even injure a person if provoked.

Construction Notice:

Parking Lot Closed September 21, 22 and 23.

Morris Arboretum’s parking lot is being repaved September 21, 22 and 23. Our parking lot is a demonstration lot for its sustainability. Installed 25 years ago as one of the first of its kind, the parking lot has filtered into the earth about 31,863,304 gallons of precipitation from the Wissahickon watershed. But the time has come for it to be renewed.

The entire parking lot will be closed September 21, 22 and 23. Auxiliary parking will be available at the bottom of the hill (near the kiosk) and shuttle service will be provided to the top of the hill. ADA access will be limited. No buses will be permitted beyond the kiosk.

We apologize for the inconvenience, but we are committed to keeping our parking lot sustainable and our visitors safe. Thanks for your patience.

The Arboretum is open as usual. Click here for hours.
