On Friday, 7 October 2011, a late-morning tour is planned of the grand Analemmatic Sundial at Longwood Gardens in nearby Kennett Square, PA. This event will include a special orientation and tour of the Longwood Gardens facilities by staff historian Colvin Randall, and will feature a talk by Dr. P. Kenneth Seidelmann who redesigned the sundial in 1975 to keep accurate Standard Mean Solar Time.
Longwood Gardens is a renowned destination for visitors from around the world. In addition to stunning gardens and fountains, Longwood is home for the 10,010 pipe Aeolian organ, the largest ever built in a residential setting and still one of the largest in the world. Scientists, engineers, and music lovers will appreciate the view of workings of the instrument from the backstage gallery.
