- New Bolton Center

Located in Unionville, the 600 acre New Bolton Center is the center for the large animal hospital and school of the University of Pennsylvania, which is located in Philadelphia, PA. It is meant to teach veterinary medical students, improve research, and help the animal agriculture community with its research. Many famous large animals such as horses, elephants and cows have been here for treatment.

The Allam House is the oldest building on the campus, dating back to 1717. It was built by an immigrant named Caleb Pusey, who arrived in America in 1682 on the ship Welcome with William Penn. The Allam House was passed down through many generations of the Pusey family and then to the Weisbrod family. In 1940 Charles Higgins bought it and had it renovated from the small farmhouse into an estate. In 1937 Effingham B. Morris gave the University of Pennsylvania a 500-acre dairy farm named Bolton Farm. The University, realizing it was not being used for the school, sold it in 1951 and used the money to buy South Brook Farm in West Marlborough Township from Charles Higgins. The farm was named New Bolton Center after the original farm the school had owned.In 1954 the center was officially dedicated to the University of Pennsylvania. At that point, the house was used for 10 years as a dormitory and office. In 1966 the farmhouse was named after the eighth dean of the school, Dr. Mark Allam.

The campus has over 70 other buildings, including a few historic buildings, a hospital for large animals, laboratories, classrooms, dormitories, and farm buildings. The large animal hospital, the George D Widener Hospital, is one of the country's main veterinary medical centers. Special areas of the hospital include: the William B Boucher Field Service provides emergency and routine health care for dairy, equine and small ruminant clients, the Connelly Intensive Care Unit/ Graham French Neonatal Section is for the intensive care unit, the Georgia and Philip Hofmann Research Center for Animal Reproduction is for evaluation and treatment of reproductive problems.

The C. Mahlon Kline Orthopedic and Rehabilitation Center is equipped with a special raft in a pool for large animals where they can safely recover from anesthesia. The animal can be operated on while laying on a heavily padded table, so the weight of the body won't crush the side the animal is laying on. From the operating table there is a monorail that carries the animal to the nearby pool. There, the animal is placed into a raft made especially for large animals. The usual time to recover takes about 15 minutes in the swimming in the pool. If the animal is staying a longer period of time, because it is not reconvered, the monorail continues into a barn where they can be lowered into a stall.

The Jeffords Treadmill Facility has Pennsylvania's only hydraulic treadmill, which is used for observing performance problems in horses. The treadmill can go up to 45 miles per hour, though it rarely reaches that speed. The horse's nostrils will be hooked up to a machine while the horse runs, breathing into the machine so the breath can be analyzed. In addition, the Moran Surgical Suite has a hydraulic surgical table for adjusting the position of large animals for surgery. The Raker Outpatient Surgical Suite has very modern video equipment to examine the upper and lower respiratory tract, esophagus and stomach.

Sports Medicine and Imaging includes nuclear medicine, radiology, cardiology, and ultrasound.
The Jean Austin duPont Library has over 30,000 volumes and receives about 500 periodical titles. It also has the Fairman Rogers Collection, which has around 1,200 rare books, the oldest dating back to the sixteenth century, about equestrian and horses.

The New Bolton Center continues to add to its facilities; it finished getting $3.1 million in 2001 to build the Scott Equine Sports Medicine Building. The new swine unit opened in January 2002, to teach students, and provide research for both the animal and human community.
