Fort Washington is a census-designated place and suburb of Philadelphia in Montgomery County, Pennsylvania, United States.

Engard purchased a 100 acres (40 ha) lot of land on what was to be named Susquehanna Road and Fort Washington Avenue.

The house built by Philip Engard is listed as the "Engard Family Home - 1765" in the Upper Dublin Township Open Space & Environmental Resource Protection Plan - 2005, as part of the Upper Dublin Historical Properties #25.

On July 17, 1856, Fort Washington was the site of one of the worst train accidents in the United States when two North Pennsylvania Railroad trains collided with one another near the Sandy Run station, later renamed Camp Hill, now the defunct Fellwick Station).

Many of the dead were children from St. Michael's Roman Catholic Church from the Kensington section of Philadelphia, who were traveling to Sheaff's Woods, a park in the Fort Washington area for a Sunday school picnic.

[4][5] On January 1, 1946, the Township of Upper Dublin was created, and in doing so, encompassed Fort Washington along with nine other communities.

The primary center of business and industry in Upper Dublin Township is the Fort Washington Office Park, which occupies 536 acres (217 ha) and contains 6,000,000 square feet (560,000 m2) of building space.

The park contains the offices of over 100 different companies, including Honeywell, Aetna, AccuWeather, Eastern National, Genworth Financial, and a suburban campus of Temple University.

The office park was also home to the corporate headquarters of CDNow, the pioneering online music retailer.

Opened in 1993 in the former Honeywell factory, the Expo Center hosted some of the region's biggest consumer and trade shows, and at 290,000 square feet (27,000 m2), was the largest such suburban venue in the northeastern United States.
