New York City was the nation's first capital (from April 1789 to July 1790) under the newly created Constitution, and is where George Washington was inaugurated (at Federal Hall on Wall Street). At the time, the city was less populous than Philadelphia, and its streets, according to the New York Times, were "unpaved, narrow and crooked, often unlighted at night and frequently impassable because of wandering pigs."
