Construction of Pennsylvania Avenue and 7th Street in 1839 with the First Unitarian Church on the northeast corner of 6th Street and Pennsylvania Avenue visible in the background Prior to the settlement of the area by European colonists, the
Piscataway tribe of
Native Americans occupied the northeastern banks of the
Potomac River, although no permanent settlements are known in the area now encompassed by the city of Washington. As the region began to be settled,
David Burnes obtained the first title to the area which would become Pennsylvania Avenue NW in 1774.
Article One, Section 8, of the
United States Constitution established a "District... [to] become the seat of the government of the United States..." The
Residence Act of 1790 (as amended), established this district and gave to the
President of the United States the authority to fix the location of the site somewhere along the Potomac River. President
George Washington chose the current site of the city in 1791, and it was surveyed later that year. At the time, it was not foreseen that the city of Washington would be coterminous with the District of Columbia, and Washington set the northern boundary of the city roughly where Pennsylvania Avenue is today. Washington chose
Pierre (Peter) Charles L'Enfant to plan the new city. Although unnamed at the time, Pennsylvania Avenue was designed in the L'Enfant plan as a critical thoroughfare for bringing existing roads into the heart of the new city. It was also designed to link the "president's palace" with the Capitol building planned for Jenkin's Hill (now
Capitol Hill). Pennsylvania Avenue was created on April 14, 1792, when the three commissioners then overseeing the District of Columbia ordered "the middle of the avenue from the president's palace to the capitol" cleared. The origin of the name "Pennsylvania Avenue" is somewhat obscure. The name was first applied to the avenue in a letter from
surveyor and
map-maker Benjamin Ellicott to the District's commissioners in December 1791. The actual clearing of Pennsylvania Avenue did not begin until spring 1796. Much of Pennsylvania Avenue below 9th Street was swampy and nearly unusable, as
Tiber Creek curved north to border the avenue at 9th Street and again at 5th and 4th Streets before actually crossing it at 2nd Street. The damp earned the street the nickname of the "Great Serbonian Bog." (This marshy area was filled in and dried beginning in 1816.) In the fall of 1800, Pennsylvania Avenue was cleared of underbrush, and a raised footpath covered in stone chips was built. A stone bridge over Tiber Creek at 2nd Street was also built during this time, being replaced by a brick arch in 1817. On March 3, 1803, President
Thomas Jefferson ordered that Pennsylvania Avenue be widened and the road completed.
Benjamin Henry Latrobe, the architect newly hired to supervise the avenue's reconstruction, built three lanes separated by four rows of
Black Poplars. Additional improvements to the street were made throughout the 19th century: The avenue was
macadamized in 1832 (and the poplars removed), repaved with round stones in 1852, and repaved with wooden blocks from 1st to 15th Streets in 1870. The wooden blocks required such extensive repair, however, that between 1876 and 1877 they were replaced with rock from 1st to 6th Streets NW, and with
grahamite asphalt from 6th to 15th Streets NW.
Growing development of the Pennsylvania Avenue district at 6th Street with the not yet finished
United States Capitol in the distance and the
National Hotel on the left The
Pennsylvania Avenue area of the city saw limited growth prior to the 1850s, although a number of firsts also occurred in the area.
James Greenleaf, an early land speculator in the city, erected the first buildings, including six
row houses, on Pennsylvania Avenue in the spring and summer of 1794 at the corner of Pennsylvania Avenue NW and 22nd Street NW, and another seven similar buildings were erected about the same time by
Walter Stewart, a
Continental Army general during the
American Revolutionary War. The "Six Buildings" erected by Greenleaf served as the first headquarters of the
United States Department of State and the
United States Department of the Navy in 1800, while one of the buildings across the street housed the
United States Department of War. Two of the city's first three street lamps were established in the area near Capitol Hill in December 1801.
Center Market, the city's first food market, was built the same year on a lot on the south side of Pennsylvania Avenue between 7th and 8th Streets. It became the hub of the city's early commercial district. Over time, the business district moved north, but its southern boundary continued to be marked by Pennsylvania Avenue. Center Market moved a block west along Pennsylvania Avenue to larger, more modern facilities in 1872. The second
inauguration of Thomas Jefferson, which occurred on March 4, 1805, was the first to host an inaugural procession down Pennsylvania Avenue. The city's first school, the Western School, opened on the south side of Pennsylvania Avenue between 17th and 18th Streets NW in January 1806. The city's first sewer pipe was laid under Pennsylvania Avenue in 1829. By 1835, Pennsylvania Avenue was largely lined by two- to four-
story Federalist row houses. The
Baltimore and Ohio Railroad converted a house at the corner of 2nd Street NW and Pennsylvania Avenue into the city's first train station. It was abandoned in 1851 when the station moved to a more long-lasting location at New Jersey Avenue and C Street NW. The same year, the National Theatre opened on December 7. It was followed by the 400-seat Odeon in 1846, the 1,000-seat Adelphi in 1847, and Metzerott Hall in the 1860s. President
Andrew Jackson approved the construction of the
Treasury Building in 1836 (it was completed the following year), but the size and height of the building forced a rerouting of Pennsylvania Avenue and blocked the view of the White House from L'Enfant's "Grand Avenue." The city's first stock brokerage was opened by William W. Corcoran at 15th and Pennsylvania Avenue in 1837. The city blocks where the
National Gallery of Art now stands became a fashionable residential area in the 1830s. on Pennsylvania Avenue around 1880 ," this area was home to numerous brothels. In the 1860s, the area saw significant deterioration despite continuing improvements to Pennsylvania Avenue itself. Pennsylvania Avenue was lit with
coal gas streetlights in 1851. The avenue was one of the few fully lit streets in the entire city of Washington. In July 1862, a horse-drawn
trolley line was built along the street between the Capitol and White House. But despite these many improvements, much of the Pennsylvania Avenue Historic Site south of Pennsylvania Avenue had become a disreputable slum known as
Murder Bay, the home to an extensive criminal underclass and numerous brothels. During the
American Civil War, so many prostitutes took up residence in Murder Bay to serve the needs of
General Joseph Hooker's
Army of the Potomac that the area became known as "Hooker's Division." Pennsylvania Avenue saw its first electric streetlights give light on October 14, 1881. A small number of additional lights north of the avenue along 10th Street NW were lit later that month. The southern part of the Pennsylvania Avenue district was flooded many times in the last three decades of the 19th century. Major floods occurred in October 1870 (during which
Chain Bridge was destroyed), February 1881, November 1887, and June 1889 (the same storm which caused the
Johnstown Flood). Floodwaters were high enough that rowboats were used on the avenue, and horse-drawn streetcars saw water reach the bottom of the trams.
D.C.'s Chinatown was established in 1884, although Chinese and other Asian immigrants began moving into the area in noticeable numbers as early as 1880. This Chinatown existed along the south side of Pennsylvania Avenue between 4th and 7th Streets, with the heaviest concentration of residences and businesses near the Center Market site where 4th Street, C Street, and Pennsylvania Avenue met. This Chinatown existed as a vibrant community until 1935, when the construction of the
National Archives Building and the
Apex Building (which houses the
Federal Trade Commission) forced the Chinatown to move to its current location on H Street NW. Limited attempts to transform the area by eliminating crime and encouraging upscale economic development occurred from 1890 to 1910. Congress approved the construction of a new, 12-story
Romanesque Revival headquarters for the
Post Office Department (to include a new central post office for the District of Columbia as well) in 1880. Construction on the
Post Office Building began in 1892 and was completed in 1899. At the time of its completion, the Post Office Building contained the largest uninterrupted enclosed space in the city. Spurred by the centennial of the transfer of the seat of government from Philadelphia to the District of Columbia, in 1900 the
United States Congress formed the Senate Park Commission (also known as the McMillan Commission after its chair, Senator
James McMillan) to reconcile competing visions for the development of Washington, D.C., and especially Pennsylvania Avenue, the
National Mall, and nearby areas. The commission's plan for development, the
McMillan Plan, proposed beautifying Pennsylvania Avenue and placing new government office buildings along a new Centennial Avenue to run the length of the National Mall. The
District Building was built in 1908 between 13 and 14th Streets NW on the south side of the avenue. Over the next few years, the President and Congress established several new agencies to supervise the approval, design, and construction of new buildings in the District of Columbia: The
Commission of Fine Arts in 1910 (to approve the design of new structures), the Public Buildings Commission in 1916 (to make recommendations regarding the housing of federal agencies and offices), and the
National Capital Parks and Planning Commission in 1924 (to oversee planning for the District). In the mid-1910s, Congress appropriated and the government spent $7 million to acquire land on Pennsylvania Avenue NW between 14th and 15th Streets NW and several blocks south. But no demolition or construction was conducted, and the government merely collected rent from tenants in the area. The effort saw success in 1926 with the passage by the
United States Congress of the
Public Buildings Act, which authorized the construction of the
Federal Triangle complex of buildings as well as a new
U.S. Supreme Court building opposite the
United States Capitol, a major extension of the
U.S. Government Printing Office building on
North Capitol Street, and significant widening of B Street NW on the north side of the National Mall (eventually renamed
Constitution Avenue). The construction of Federal Triangle enabled the Pennsylvania Avenue National Historic Site to become the "monumental core" of the city. ==Historic designation and rejuvenation==
