Thomas Edison National Historical Park

State: New Jersey. Type: National Park Service unit in West Orange, Essex County, preserving Thomas Edison's laboratory complex and Glenmont estate. Originally designated Edison Home National Historic Site (Dec. 6, 1955) and Edison Laboratory National Monument (July 14, 1956); combined as Edison National Historic Site on Sept. 5, 1962; renamed Thomas Edison National Historical Park on March 30, 2009. Size: 21.25 acres. Address: 211 Main Street, West Orange, NJ 07052.

Thomas Edison National Historical Park preserves the laboratory complex in West Orange where Edison and his staff worked for more than 40 years, plus Glenmont, the Queen Anne-style mansion where he lived with his family. The 1887 laboratory complex, designed by architect Henry Hudson Holly, once held more than a dozen interconnected buildings supporting research into electricity, sound recording, motion pictures and other fields, and it includes a reconstruction of the Black Maria, widely described as the world's first movie studio. Glenmont, built 1880-1882 and purchased by Edison in 1886, sits a short distance away and retains period features such as early central heating and indoor plumbing that were considered advanced for their time. The site's federal designations trace back to 1955-56 and were consolidated and renamed over subsequent decades, culminating in the 2009 renaming to Thomas Edison National Historical Park. Visitors typically see both the laboratory complex and, with a separate grounds pass obtained on-site, Glenmont's grounds and guided house tours.

The park is located at 211 Main Street, West Orange, New Jersey 07052, in Essex County. Glenmont, Edison's residence, is a short distance from the main laboratory complex within the same historical park.

West Orange shares northern New Jersey's humid continental climate, with cold winters and warm, humid summers. Since the laboratory buildings and Glenmont's interior are toured indoors, weather has less impact on a visit here than on outdoor-heavy destinations, though walking between buildings is more comfortable outside of peak summer heat or winter cold.

Spring and fall generally offer the most comfortable weather for walking between the laboratory complex and Glenmont. Because specific operating days/hours could not be confirmed during this research, check the park's current schedule before planning a season or day of travel.

Edison's West Orange laboratory complex, built in 1887 and designed by architect Henry Hudson Holly, replaced his earlier Menlo Park lab and became the base for more than 40 years of research producing major innovations including improved phonographs and sound recordings, motion picture cameras, and the nickel-iron alkaline battery. The complex's Black Maria building, recreated on-site, is described as the world's first movie studio. Glenmont, a Queen Anne-style mansion built 1880-1882 for an earlier owner, was purchased by Edison in 1886 for $125,000 as a home for his family and featured then-advanced conveniences such as gravity-convection central heat and indoor plumbing. The federal government first protected the site in pieces, designating Edison Home National Historic Site on December 6, 1955 and Edison Laboratory National Monument on July 14, 1956; these were merged into Edison National Historic Site on September 5, 1962, and the unit was renamed Thomas Edison National Historical Park on March 30, 2009. The National Park Service reports approximately 22,370 visitors in 2025.

Visitors can tour the laboratory complex's machine shops and research buildings, see the Black Maria motion-picture studio replica, and take a guided tour of the Glenmont mansion (accessed via a separate grounds pass obtained at the Laboratory Complex Visitor Center). Audio tours are available online, and the park runs group tour programs and a Junior Ranger program for younger visitors. The visitor center also holds a collection of more than 6,000 historical photographs related to Edison's work.

The Laboratory Complex (1887) contains more than a dozen buildings that supported Edison's research, including machine shops and the Black Maria replica. Glenmont, Edison's Queen Anne-style family home purchased in 1886, is the park's other major stop, along with its poured-concrete garage housing vintage vehicles associated with the Edison family.

The park is located in West Orange, New Jersey, in Essex County, within the New York metropolitan area. Visitors typically drive or use rideshare/taxi service to reach 211 Main Street; specific public-transit routing to the site was not confirmed during this research, so check the park's official directions page before planning transit-based travel.

Operating hours and any seasonal closures could not be confirmed during this research; the park's own pages direct visitors to its "Basic Information" and "Hours" pages, which returned errors when checked. Call the park directly at 973-736-0550 x11 or check nps.gov/edis before visiting.

Specific ticket prices could not be confirmed during this research. The National Park Service notes that staff collect entry fees and issue Interagency Passes at the Visitor Center, and that visiting Glenmont requires obtaining a separate Grounds pass at the Laboratory Complex Visitor Center first, but exact fee amounts were not available from the pages retrieved. Confirm current pricing directly with the park before visiting.

Budget at least two to three hours to see the laboratory complex and take a Glenmont tour; a shorter visit is possible if focusing on just one of the two main sites.

West Orange and the surrounding Essex County suburbs offer a range of chain hotels convenient for visitors, given the area's location within easy reach of Newark and the greater New York City metropolitan region. Many visitors also base themselves in Newark or nearby towns and visit the park as part of a broader day trip.

West Orange and neighboring towns along the Main Street corridor offer a range of casual dining options typical of northern New Jersey suburban commercial strips. The park itself does not appear to operate an on-site restaurant based on the sources reviewed, so most visitors plan to eat before or after their visit nearby.

The park sits within Essex County, a short drive from Newark and other North Jersey attractions, making it easy to combine with a broader day trip in the greater Newark/New York metropolitan area for visitors extending their stay.

The park sits within the greater Newark/New York metropolitan area; Newark Liberty International Airport is the nearest major airport. Specific NJ Transit bus or rail routing directly to the park was not confirmed during this research, so most visitors are expected to arrive by car or rideshare.

Because Glenmont access requires a separate grounds pass obtained at the Laboratory Complex Visitor Center, plan to start your visit there rather than heading straight to Glenmont. As with any historic-house tour, follow posted guidance about touching artifacts and furnishings. For any emergency, dial 911.

Comfortable walking shoes for moving between the laboratory complex and Glenmont, a light jacket for climate-controlled interiors, and a camera for the historic machine shops and mansion interiors are all worth packing.

Start at the Laboratory Complex Visitor Center, since a Glenmont Grounds pass must be obtained there before proceeding to the mansion. Call ahead (973-736-0550 x11) to confirm current hours, fees and tour availability, since these details were not confirmed from the park's web pages during this research. Group tours require advance reservation.

Dial 911 for any emergency. The park's visitor contact line is 973-736-0550 x11, per its official information; messages are checked when the park is open.
