Glenmont is the Victorian Queen Anne mansion in Llewellyn Park where Edison and his wife Mina lived from 1886 until his death. The house is part of the national historical park and can be visited on ranger-led tours. The interior is preserved largely as it appeared in the early 20th century: the elaborate Victorian decoration that was fashionable when the house was built, gradually overlaid with Edison's later acquisitions and the couple's personal effects.
The garage is a particular highlight, containing Edison's electric cars — remarkable objects in themselves, built by Edison as practical demonstrations of the nickel-iron battery he invented. The garden is peaceful and well maintained, and the views from the property across Llewellyn Park's landscaped grounds are a reminder of how prosperous and rural West Orange was in the Gilded Age. Tours must be booked in advance; check the national park website for current schedules.
