Map - Doylestown, Pennsylvania (Doylestown)

Doylestown is a borough and the county seat of Bucks County in Pennsylvania, United States. It is located 20 mi northwest of Trenton, 25 mi north of Center City, Philadelphia, 27 mi southeast of Allentown, and 66 mi southwest of New York City. It constitutes part of the Delaware Valley (i.e. the Philadelphia metro area).

As of the 2020 census, the borough population was 8,300.

Like most of the region, the area of Doylestown was inhabited by the Lenape people until the arrival of the Europeans.

Doylestown's origins date to March 1745 when William Doyle obtained a license to build a tavern on what is now the northwest corner of Dyers Road and Coryell's Ferry Road (now Main and State Streets). Known for years as "William Doyle's Tavern," its strategic location, at the intersection of the road (now U.S. Route 202) linking Swede's Ford (Norristown) and Coryell's Ferry (New Hope) and the road (now PA Route 611) linking Philadelphia and Easton, allowed the hamlet to grow into a village. The first church was erected in 1815, followed by a succession of congregations throughout the 19th century.

A second inn, the Sign of the Ship was established in 1774, built diagonally across from the Doyle Tavern. Samuel Flack was innkeeper in 1778.

As the population of Central and Upper Bucks County grew throughout the 18th and into the 19th century, discontent developed with the county seat's location in Newtown, where it had been since 1725. Eight petitions with a total of 184 signers were submitted to the General Assembly, some as early as 1784, requesting the move of the county seat to Doylestown. Among the signers were Andrew Armstrong, John Armstrong, John Davis, Andrew Denison, Jesse Fell, Joseph Fell, John Ingham (of Ingham Springs), Michael Frederick Kolb, Zebulon M. Pike (of Lumberton), Samuel Preston, Robert Shewell, Walter Shewell, and Fulkerd Sebring. The General Assembly approved the move by an Act on February 28, 1810, and the first Court session was opened on May 11, 1813. An outgrowth of Doylestown's new courthouse was the development of "lawyers row", a collection of Federal-style offices. One positive consequence of early 19th-century investment in the new county seat was organized fire protection, which began in 1825 with the Doylestown Fire Engine Company.

A post office was established on January 1, 1802. Charles Stewart, the first postmaster, carried letters to recipients in the bell-shaped crown of his high beaver hat as he walked about the village. When Stewart died on February 7, 1804, his son-in-law Enoch Harvey became the next postmaster. On October 9, 1804 Harvey advertised in the Pennsylvania Correspondent, published in Doylestown, of a list of letters remaining in the post office for Wm. R. Hanna, Esq., Newtown; Doct. Felix Robertson, Bucks County; Robert Wehir, Shamony, Bucks County; Robert A. Farmer, Esq., Birdsborough; Israel Childs, Buckingham.

A bill to erect Doylestown into a borough was introduced into Legislature in February 1830, but failed, as well as a second attempt in the session of 1832. "An Act to erect the Village of Doylestown, in the County of Bucks, into a Borough" was passed and signed into law by Governor Joseph Ritner on April 16, 1838.

An electric telegraph station was built in 1846, and the North Pennsylvania Railroad completed a branch to Doylestown in 1856. The first gas lights were introduced in 1854. Because of the town's relatively high elevation and a lack of strong water power, substantial industrial development never occurred and Doylestown evolved to have a professional and residential character.

During the mid-19th century, several large tracts located east of the courthouse area were subdivided into neighborhoods. The next significant wave of development occurred after the Civil War, when the 30 acre Magill property to the southwest of the town's core was subdivided for residential lots.
