What Washington D.C. looked like in the late 19th Century

Washington D.C. did not become the nation’s capital overnight. Congress passed the Residence Act on July 17, 1790, establishing a permanent seat for the federal government. The new district was named in honor of Christopher Columbus, while the city itself was named after President George Washington. What followed was decades of slow, often painful growth — shaped by politics, war, and an ambitious drive to build something worthy of a young republic.

By the 1830s, railroads had connected Washington to the rest of the country. Tourists arrived in growing numbers, and the city’s social scene expanded as congressional families took up residence. Streets filled with new faces, and Washington began to feel less like a construction site and more like a functioning capital. But the city’s greatest test was still ahead.

When the Civil War broke out in 1861, Washington was transformed almost overnight into a military hub. Troops flooded the city. Tent camps appeared on the outskirts, turning farmland and open fields into temporary quarters for thousands of Union soldiers. The 31st Pennsylvania Infantry — later reorganized as the 82nd — set up camp at Queen’s Farm near Fort Slocum, one of dozens of fortifications built to defend the capital.

Security around the city was tight. Guards were posted at ferry landings and key crossings, checking passes and controlling who entered or left the capital. The Confederate capital in Richmond, Virginia, sat less than 100 miles away, making Washington both a symbolic and strategic target. The city could not afford to let its guard down.

Alongside the military buildup came an explosion of hospitals. Harewood Hospital, one of several large facilities established in the city, treated thousands of wounded Union soldiers. Patients lay in rows under mosquito netting, cared for by nurses and volunteers working in difficult conditions. The Armory Square Hospital, the Second Corps Hospital, and Campbell Hospital were among the other sites that turned Washington into a city of the sick and wounded.

Relief organizations played a major role in supporting both soldiers and the city’s swelling population. The U.S. Sanitary Commission operated storehouses and lodges throughout Washington, including a Home Lodge for Invalid Soldiers on North Capitol Street. Workers there provided food, shelter, and care for men too sick or injured to return to active duty. The United States Christian Commission maintained its own office in the city, staffed by volunteers who distributed supplies and provided spiritual support to troops.

The war also transformed Washington’s infrastructure. Government repair shops, quartermaster offices, and supply depots operated throughout the city. The Smithsonian Institution’s castle building, constructed in the 1840s, stood as a reminder of the capital’s pre-war ambitions, while newer structures rose quickly to meet wartime demand. Arsenal buildings along the Potomac stored weapons and ammunition. The Old Capitol Prison held Confederate prisoners and suspected spies.

The U.S. Capitol itself was still under construction during the war years. Cranes and scaffolding surrounded the dome as workers pushed forward with the building’s expansion, even as soldiers camped on the grounds below. Lincoln insisted the construction continue throughout the conflict, viewing it as a statement of national resolve. By 1863, the dome was nearing completion, and the building’s new wings were taking shape.

On March 4, 1861, Abraham Lincoln delivered his first inaugural address at the Capitol — an event that drew a massive crowd at a moment of deep national anxiety. Four years later, days after the war effectively ended, Lincoln was shot at Ford’s Theatre on April 14, 1865. Guards were posted at the theater immediately after the assassination, and the building was shut down. The nation’s capital was thrown into shock.

The investigation and prosecution of Lincoln’s assassination conspirators moved quickly. Four people — Mary Surratt, Lewis Payne, David Herold, and George Atzerodt — were convicted and sentenced to death. On July 7, 1865, General John F. Hartranft read the death warrant to the condemned at Arsenal Prison. The executions were carried out by hanging that same day at what is now Fort McNair.

With the war over, Washington held the Grand Review of the Armies on May 23–24, 1865. Hundreds of thousands of Union soldiers marched down Pennsylvania Avenue in a two-day celebration. General John A. Logan’s 15th Army Corps was among the units that passed in review near the Treasury building, drawing enormous crowds of spectators lining the avenue.

In 1871, Washington residents were granted self-governing rights for the first time. The territorial government that took office oversaw a sweeping upgrade of the city. Streets were paved and lit. Sewer systems were expanded. Schools and markets were built. More than 50,000 trees were planted across the city. Washington began to look and function like a true capital, not just a wartime garrison.

The Washington Monument, which had stood unfinished for decades due to funding shortfalls and the interruption of the Civil War, was finally completed in 1884. As late as 1860, the structure sat at roughly one-third of its final height, a stubby marble stump visible from much of the city. The Library of Congress opened its doors in 1897, and that same year the American Institute of Architects was formally established in Washington.

By the 1890s, Washington had developed into a city with a vibrant social and cultural life. Social clubs, arts organizations, and professional societies were active across the city. Photographers like Frances Benjamin Johnston documented daily life in the capital, capturing everything from government buildings to portraits of Washington residents. Johnston was known as much for her bold personal style as for her camera work, and she operated out of her own studio in the city.

The city’s major institutions took on a more polished appearance by the late 1890s. The U.S. Treasury building, the Smithsonian Institution, the Army and Navy Building, and the Soldiers’ Home were all landmarks by this point. The East Room of the White House had been refurbished. The old Supreme Court chamber inside the Capitol still stood as it had for decades. Washington was becoming a city that matched its ambitions.

Markets, commerce, and everyday life filled the streets of the city. The Center Market on Pennsylvania Avenue was one of the busiest spots in Washington, with wagons arriving daily to supply the capital’s growing population. The Agricultural Department occupied a prominent building by the 1890s, reflecting the federal government’s expanding role in managing the country’s land and resources.

Photography itself was thriving in the city. At J.F. Jarvis’s photo store, glass photographic negatives were sun-printed on the roof — a process that required direct sunlight to expose the prints. Alexander Gardner operated a gallery at 7th and D Streets, where many of the Civil War’s most important images were displayed and sold. The camera had become a key tool for recording the life of the capital.

Political life, too, was on full display. In 1881, Chief Justice Morrison R. Waite administered the oath of office to James A. Garfield on the east portico of the Capitol. Public events, inaugurations, and official ceremonies were part of the rhythm of the city. Thaddeus Stevens, the radical Republican congressman, lay in state in the Capitol Rotunda in 1867 — one of the first people to receive that honor.

The following photographs span three decades — from the early years of the Civil War through the close of the 19th century. Together, they show a city that absorbed enormous pressure and kept building.
