A building or a city?
A capitol is a building, and a capital is a “city where the seat of government is located,” according to the Associated Press Stylebook. Remembering these sentences may help you keep the two spellings straight:
Montgomery is the capital of Alabama. The city’s first capitol was built in 1847.
Our state capital is, of course, Denver. The Colorado Capitol, not far from the 16th Street Mall, is a beautiful building that is always worth a visit.
The gold-plated dome of the Colorado Capitol symbolizes our state’s “Gold Rush” days.
