September 18 is best known for 1793, when George Washington laid the cornerstone of the U.S. Capitol. The date also brought the Mukden Incident in 1931, which opened Japan’s takeover of Manchuria, and Scotland’s 2014 vote to stay in the United Kingdom.
The big story: Washington lays the Capitol cornerstone (1793)
The Capitol got off to a bumpy start. Pierre Charles L’Enfant, the French engineer who laid out the new federal city, was fired in 1792 after clashing with the commissioners in charge. A design contest for the Capitol followed, and William Thornton’s entry won. On September 18, 1793, President Washington set the building’s cornerstone in place. Then came the slow part. Congress moved into the finished north wing in November 1800. The House got the south wing in 1807, and it was done in 1811. Three years later, on August 24, 1814, British troops set the Capitol on fire during the War of 1812, and a rainstorm kept it from burning to the ground. Congress met in temporary quarters until 1819. A major expansion began in the 1850s, paused in 1861 when Union soldiers used the building as barracks and a hospital, and eventually produced the cast-iron dome. All told, the building took close to a century to finish.
