Neoclassical architecture: characteristics and examples, from the Capitol to Saint Petersburg

Architecture · 4 September 2026

Neoclassical architecture is the return to the forms of ancient Greece and Rome that began in the 1750s and dominated public building until the 1850s, then came back as the official style of the United States from the 1890s to the 1940s. Its marks are a columned portico with a triangular pediment, symmetry, smooth walls with little ornament, a dome for the most important buildings, and proportions taken from Roman temples and from Vitruvius. It replaced Baroque and Rococo as a deliberate return to order and reason, which is why the new American republic adopted it for its Capitol, its president's house and its first universities. Below are the seven characteristics, the buildings that show them in the Buildings by style collection, the American story, and the differences from the styles it is confused with.

The seven characteristics

1. The temple front. A portico of columns, usually six or eight, carrying an entablature and a triangular pediment, placed on the entrance facade. The Panthéon in Paris (1790) and the Madeleine (1842), a complete Roman temple with 52 columns, are the pure form.
2. The orders used correctly. Doric, Ionic and Corinthian columns with the proportions measured on real ruins by Stuart and Revett in Athens (1762) and by Piranesi in Rome, not the free variations of the Baroque.
3. Symmetry and the axis. A central block with equal wings; the entrance on the axis; windows in even rows.
4. Smooth, plain walls. Ornament is limited to the orders themselves, a cornice, a frieze; the wall is a calm surface, often rusticated only at the base.
5. The dome. On the building that matters most in a city: a drum with columns and a dome, following the Pantheon in Rome and Saint Peter's, as at the United States Capitol and Saint Isaac's Cathedral.
6. Colonnades and long horizontals. Facades stretched into rows of columns: the 96 columns of Kazan Cathedral in Saint Petersburg, the 44 of the British Museum, the 580-metre curve of the General Staff Building.
7. Monuments. Triumphal arches, columns and gates copied from Rome: the Arc de Triomphe, the Brandenburg Gate, the Narva Gate.

Where it came from

Two things happened in the 1750s. Pompeii and Herculaneum were being dug up, and the first measured drawings of Greek temples were published, so for the first time architects could see what antiquity actually looked like rather than the Renaissance idea of it. At the same time Enlightenment writers, above all the German scholar Winckelmann, praised Greek art for "noble simplicity and quiet grandeur" and condemned Baroque as decadent. Architecture followed philosophy: Jacques-Germain Soufflot's Panthéon in Paris, begun in 1757, is the first great Neoclassical building, a Greek cross with a Corinthian portico and a dome, built as a church and turned by the Revolution into a temple of great men. In Britain Robert Adam decorated Kedleston Hall and dozens of houses in a light Roman manner; in Germany Carl Gotthard Langhans copied the Athenian Propylaea for the Brandenburg Gate (1791).

Why the United States chose it

The founders read Roman history and saw themselves as a new republic; Greek and Roman forms said "republic" the way Gothic said "church" and Baroque said "king". Thomas Jefferson, who had studied the Maison Carrée in Nîmes, designed the Virginia State Capitol (1788) as a Roman temple, his own house Monticello (1809) after Palladio, and the University of Virginia as a lawn of pavilions around a Pantheon. Washington, D.C. was planned around two Neoclassical buildings: the White House (1800) by James Hoban, based on Leinster House in Dublin, and the Capitol, whose cast-iron dome of 1866 was finished during the Civil War as a sign that the Union would stand. From then on, every state capitol, most courthouses, banks, museums and post offices in the country took a portico and, if the budget allowed, a dome.

The second American wave: Beaux-Arts and the City Beautiful

After the 1893 Chicago World's Fair, whose white Neoclassical pavilions were nicknamed the White City, American architects trained at the École des Beaux-Arts in Paris rebuilt the country's institutions in a grander, more Roman version: the New York Public Library (1911), Grand Central Terminal (1913), the Jefferson Memorial (1943), and the Lincoln Memorial (1922), a Doric temple with 36 columns for the 36 states at Lincoln's death. The Federal Triangle in Washington and the Supreme Court building (1935) are the last of this wave. It ended when modernism arrived and glass boxes became the language of government after 1945.

Neoclassicism in Russia

Catherine the Great and Alexander I turned Saint Petersburg into the largest Neoclassical city in the world. Ivan Starov's Tauride Palace (1789) set the model for country houses across the empire; Andreyan Zakharov's Admiralty (1823) is a 407-metre facade with a gilded spire; Voronikhin's Kazan Cathedral (1811) wraps Nevsky Prospekt in a colonnade; Carlo Rossi's General Staff Building (1829) closes Palace Square with a triumphal arch; Montferrand's Saint Isaac's (1858) took forty years and 48 granite columns of 114 tons each. In Moscow, Bazhenov's Pashkov House and the Bolshoi Theatre with its quadriga of Apollo belong to the same line. The Russian version is called Empire style after Napoleon's France: military trophies, laurel wreaths and the eagle in the ornament.

Neoclassical vs Greek Revival, Federal, Beaux-Arts and Baroque

• Greek Revival (1820–1860) is Neoclassicism that copies Greece rather than Rome: Doric columns without bases, no domes or arches, white paint. In the US it is the style of plantation houses, Southern courthouses and thousands of farmhouses with a pediment over the front door. Walhalla near Regensburg, a copy of the Parthenon, is the European extreme.
• Federal style (1780–1830) is the early American version, lighter and more delicate, with fanlights over the doors and oval rooms, closer to Robert Adam than to Rome: the older houses of Boston, Salem and Charleston.
• Beaux-Arts (1880–1930) is Neoclassicism enlarged and enriched: paired columns, sculpture, grand stairs, Roman scale. The New York Public Library and Grand Central are Beaux-Arts; the Virginia Capitol is not.
• Baroque uses the same columns and domes but bends and stacks them: curved facades, oval plans, gold. Neoclassicism straightened all of that out. Details in Baroque architecture.
