You are in front of the popular Alameda Park, constructed in 1596. La Plaza de San Blas is practically the entrance to the city center. Then you get to the Plaza del Teatro and take busy Guayaquil Street towards the Plaza Grande. Near this square you'll will find the Palacio de Gobierno—the president's house, also known as Palacio de Carondelet—El Palacio Municipal, the Cathedral, and La Iglesia de San Francisco, among other buildings which constitute the treasures of Old Quito.
