Step 1 : Introduction to the question "Where is the oldest state capitol building still in use?"
...Colonial history still stands in Maryland. Its historical state capitol building – Maryland State House – in Annapolis is the oldest state capitol still in legislative use. Built in 1772, Maryland State House has seen some legislative action in its day. The Treaty of Paris, which ended the Revolutionary War, was ratified there by Congress on January 14, 1784. When you visit the Capitol, you can also check out the many other historical buildings in Colonial Annapolis Historic District, including St. Anne’s Episcopal Church, the Old Treasury, and dozens of pre-Revolutionary homes, including those of Samuel Chase, Charles Carroll, and William Paca, three original signers of the Declaration of Independence.
