In 1904, architect Will Price converted an existing circa-1790 stone barn into studios for the artists Charles H. and Alice Barber Stephens. Appended to this, he designed a rambling fieldstone-and-stucco house, including a 3-story octagonal stair tower that joined the wings and served all five levels.

Price, a founder of Rose Valley, attempted to create a community of artists and artisans working side by side under the principles of the Arts and Crafts Movement. These included truth in the use of materials, traditional craftsmanship using simple forms, and often medieval, romantic or folk styles of decoration.

​

At the edge of the property, along Rose Valley Road, is a 1926 Pennsylvania State historic marker, commemorating an important Native American trading route, the Great Minquas Path, that ran nearby. Charles Stephens designed the bas-relief on the marker, and Albert Laessle created the beaver sculpture below the plaque.

The Printzhof, located in Governor Printz Park in Essington, was the home of Johan Björnsson Printz, governor of New Sweden.

In 1643, Johan Printz moved his capital from Fort Christina (located in what is now Wilmington, Delaware) to Tinicum Island. At that time Fort Gothenburg was established in addition to Printz’s dwelling and headquarters. Two years later a fire swept over the newly established settlement. The Printzhof was reconstructed more solidly and lavishly. The two-story log structure contained lumber sent from Sweden, glass windows and lavish draperies.

Johan Björnsson Printz, his wife and younger children returned to Sweden during 1653. The Dutch West India Company subsequently captured the Swedish colony in 1655. Armegott Printz, the eldest daughter of Governor Printz, had married his successor, Lt. Johan Papegoja. She remained at The Printzhof even after the Dutch conquest. During 1662, she sold the estate for a partial down payment with the remainder due when she reached The Netherlands. When payment was refused, she returned to reclaim possession of her property. Ten years later in 1672, the Governor and Council ruled Armegott Printz should be in possession of the property. She subsequently sold the estate a second time and returned to Sweden where she died on November 25, 1695 at Läckö Castle.

Today, the Printzhof’s stone foundations are the only remains of the settlement. The Printzhof site is located near the intersection of Taylor Avenue and Second Street in Essington. The site was declared a National Historic Landmark in 1961.

The Crozer Theological Seminary was a multi-denominational religious institution located in Upland, Pennsylvania.

After 1970, when the seminary merged with institutions in Rochester, New York, the Old Main building was used for Crozer Hospital (now part of Crozer-Chester Medical Center.) It is a three-story, "F"-shaped, stucco coated stone building. It has three pavilions connected by a corridor with flanking rooms. Each of the pavilions is topped by a gable roof and cupola, the largest cupola being on the central pavilion. Most recently, it was used for medical offices associated with the center.

Idlewild is a historic building near Media, Pennsylvania, designed by the Victorian-era Philadelphia architect Frank Furness as a summer cottage for himself and his family. He spent summers there until his death in 1912.

The house was built about 1890 on the grounds of the Idlewild Hotel, which Furness had designed in 1886. This was a mile west of "Lindenshade," the Wallingford summer house of his brother, Shakespearean scholar Horace Howard Furness. It was also a short walk to the Moylan-Rose Valley train station, which enabled him to commute to his architectural office in Philadelphia.

"Idlewild" is constructed with a stone basement and brick first floor. The upper floors are framed in wood and clad with cedar shingles. It has a wrap-around covered porch, high-ceilinged rooms, and an irregular roofline with variously shaped windows and eyebrow dormers. Furness placed the service rooms and front and back stairs (with a shared landing, as at the Emlen Physick House) at the front. This increases the privacy of the rooms behind, and the visual interplay between the differing scales of the "service tower" and main house gives vibrancy to the façade.

The basic form of the house – a multi-storied, semicircular apse springing from an anchoring block, with the entrance at their juncture – is closely related to Furness's 1888 design for the University of Pennsylvania Library (now the Fisher Fine Arts Library). There, the architect placed the grand staircase in a tower at the front, separating circulation to the building's upper stories from the reading rooms behind. The library's two-story, ovoid-shaped Rotunda Reading Room is wrapped by an arcing cluster of one-story seminar rooms. "Idlewild'"s porch echoes this, wrapping around the house's ovoid parlor. Furness played with similar volumes in his design for the Bryn Mawr Hotel (1890-91). The library has been described as "a collision between a cathedral and a train station."

The Furnesses lived in Philadelphia during the winter, but summered in more informal cottages.

It was listed as a National Historic Landmark in 2013.

Wayne Station is a commuter rail station located in the western suburbs of Philadelphia at North Wayne Avenue & West Avenue in Wayne. It is served by most Paoli/Thorndale Line trains.

Wayne Station was built by the Pennsylvania Railroad from 1882 to 1884, on a design by Washington Bleddyn Powell. The original builder was William H. Bilyeu. It consists of two Victorian buildings flanking the rail lines and connected by an underground tunnel.The station building was restored from 1998 to 2010 with significant local community support and funding. The year after this restoration project began, the station was listed on the National Register of Historic Places. The scope of this restoration included repair or replacement of the chimney, masonry, windows, doors, and the retaining wall.

SEPTA began a $22.7 million second phase of improvements that included roof replacement, repairs to the masonry and structural members, and other upgrades to the station building. The outbound shelter, dating from about 1890, was disassembled and completely rebuilt, mostly with new materials. In addition, ADA-mandated improvements including new high-level platforms, stairs and ramps to the platforms, building modifications, lighting, handrails, and signage were installed. The new platforms, on both the inbound and outbound sides east of the station building, meant that trains no longer stop in front of the station itself, except in special cases.

Rose Valley is a small, historic borough in Delaware County, Pennsylvania, United States. Its area is 0.73 square miles, and the population was 913 at the 2010 census. The area was settled by Quaker farmers in 1682, and later water mills along Ridley Creek drove manufacturing in the nineteenth century.

In 1901 Rose Valley was founded as an Arts and Crafts community by architect Will Price, who bought 80 acres of land around the former Rose Valley textile mill. Price was a follower of Henry George's economics (Georgism). Price also co-founded Arden, Delaware, a utopian single tax community based on Henry George's economic model. Nevertheless, the Georgist single-tax ideal was never implemented in Rose Valley. Crafts works soon foundered, leaving a legacy of impressive architecture, a preserved landscape, and a regional theatre, the Hedgerow Theatre (founded in 1923), as well as an artistic community that includes writers, painters, and architects. As a former mayor said, "Rose Valley is an island of non-conformity." 

The Rose Valley Historic District, covering essentially all of the borough, was listed on the National Register of Historic Places in 2010.

The house was added to the National Register of Historic Places in 1986.

The Philadelphia Lazaretto was the first quarantine hospital in the United States, built in 1799, in Tinicum Township. The site was originally inhabited by the Lenni Lenape, and then the first Swedish settlers in America. Nearby Province Island was the site of the confinement of the Christian Moravian Indians who were brought there under protective custody from Lancaster, PA in 1763 when their lives were threatened by the Paxton Boys.
