Construction of the United States Capitol began in 1793 under architect William Thornton, with the building first occupied by Congress in November 1800. The structure has since undergone multiple expansions and reconstruction after British forces burned the interior on August 24, 1814, during the War of 1812.
The most dramatic physical transformation came under architect Thomas U. Walter, who designed the current cast-iron dome (1855–1866) and extended the Senate and House wings. Work on the dome continued throughout the Civil War at President Lincoln's insistence—he reportedly said, 'If people see the Capitol going on, it is a sign we intend the Union shall go on.'
When the Civil War began in April 1861, the Capitol was transformed into a military facility. By the summer of 1861, it served as barracks for Union volunteers, with soldiers camping in the Rotunda and corridors. In 1862, the building became a temporary hospital, with more than 1,500 cots placed in Statuary Hall, the Rotunda, and committee rooms. Bread was baked in the Capitol's basement ovens to supply Union troops throughout the region. Hundreds of soldiers died within the building's walls during this period.
The Capitol Visitor Center, which opened in 2008, provides underground access to exhibits spanning the building's 220-plus year history. The Capitol has been the site of two deaths of sitting members of Congress on the premises, including former President John Quincy Adams, who suffered a stroke on the House floor on February 21, 1848, and died two days later in the Speaker's Room.

The United States Capitol has accumulated paranormal legends over more than two centuries, several of which are documented in official and academic sources rather than merely anonymous submissions.
The Capitol's most famous entity is the Demon Cat, known as 'D.C.,' a spectral black feline that has been reported since at least 1862 when Union soldiers guarding the building claimed to encounter an ordinary cat that would swell to enormous proportions before pouncing. Night watchmen's reports documented the creature appearing near the basement crypt. Legend holds that D.C. appears before national catastrophes—accounts place it before Lincoln's assassination (1865), the 1929 stock market crash, and President Kennedy's assassination (1963). The Architect of the Capitol's official blog has documented this tradition.
Former President John Quincy Adams served as a Massachusetts congressman after his presidency and collapsed on the House floor on February 21, 1848, after voting against a resolution to honor officers of the Mexican-American War—his final act reportedly a resounding 'No!' Congressional staff and Capitol Police have claimed to hear this exclamation echoing in the old House chamber (now Statuary Hall).
The Civil War hospital period generated multiple ghost traditions. A Union soldier in a blood-soaked uniform has been reported in the Capitol's basement asking for water and his mother—consistent with the hundreds of soldiers who died in the building during 1862. The phantom smell of fresh-baked bread is occasionally reported in corridors near the former basement ovens.
Other reported entities include John Lenthall, a Capitol construction worker who died in 1808 when an arch collapsed against his warnings, said to have cursed the building with his dying breath; William Taulbee, a congressman shot on the Capitol stairs in 1890 whose ghost allegedly trips reporters; and the ghost of John "Bishop" Sims, a formerly enslaved man who escaped bondage in 1861 and spent decades as the Senate's beloved barber, dying in 1934 at age 91 — his old spirituals said to drift through the halls near the former Senate barbershop.

Winston-Salem, NC
The Salem Tavern was built in 1784 to serve travelers stopping in the Moravian settlement at Salem, North Carolina. The Moravian congregation built and operated the tavern — a common enterprise in Moravian settlements — as a source of revenue and a place of hospitality for outsiders. President George Washington lodged here in May 1791 during his Southern Tour, an event documented in his own diary.
Charleston, SC
Magnolia Plantation was established in 1676 by Thomas and Ann Drayton, English settlers from Barbados, and remains under the control of the Drayton family after fifteen generations. The plantation's wealth derived from Carolina Gold rice cultivated by enslaved Africans. Magnolia opened its gardens to the public in 1871, making it one of the oldest public gardens in the United States.
Staunton, VA
The American Hotel was built in 1855 by the Virginia Central Railroad as a traveler's accommodation near Staunton's rail connections. When the Civil War reached the Shenandoah Valley, the hotel was converted into a Confederate receiving hospital in 1862. During Union General David Hunter's 1864 Shenandoah campaign — which burned several structures in the area — the American Hotel was spared. The basement was used as a morgue during the hospital period. President Ulysses S. Grant visited in 1869.
