The main pedestrian street of the old city, running from the reconstructed colonial City Gate in the north to the central plaza in the south — about six blocks of colonial-era buildings now housing shops, small museums, restaurants and historic sites. It is car-free during the day and is where most visitors to the old city end up spending the bulk of their time.
Along the way you'll pass the Oldest Wooden Schoolhouse (a cramped cedar-and-tabby structure from the early 1700s), the Colonial Spanish Quarter Museum, the Avero House, and the Arrivas House — all clustered within a few blocks and all on the National Register of Historic Places. The southern end of the street opens into the Plaza de la Constitución, the original town square where the Cathedral Basilica and Government House face each other across a small park. The street gets very crowded in summer and on weekends, but early morning it has a genuine atmosphere and the architecture speaks for itself.
