Royal Street between Government and Church Streets 

In 1872, the new Carnival Association began the tradition of establishing a mock court of royalty, which would lead each year’s celebration. In keeping with this theme, the parade of this royal court stopped here in front of the courthouse, to toast the mayor of the city. The mayor at that time traditionally turned over the key to the city to the king of Mardi Gras and his court, as he still does today, so that mystic revelry may take over the city for one day of the year.
