The Capitol's Cornerstone

Ceremonies to commemorate the construction of a great public building can be traced to the ancient world and were particularly important to builders in the Middle Ages. The laying of a cornerstone is a symbolic act that celebrates humanity’s need to build and be remembered. On September 18, 1793, President George Washington laid the Capitol’s cornerstone in a ceremony attended by representatives of Masonic lodges from Maryland and Virginia, an artillery company, the city commissioners, and local residents.
