The Old Town of San Sebastian is tucked between the base of Monte Urgull and Alameda del Boulevard, and is one of the most popular places to see and be seen for both tourists and locals alike.
The center of the Parte Vieja is the arcaded Plaza de la Constitución, a large public space that once hosted bullfights while the spectators watched from the rows of balconies above.
Notable buildings nearby include the Neoclassical municipal library and the Pescadería (Fish Market). Also near the Plaza de la Constitución is the 16th-century Iglesia de San Vicente; this Gothic church is San Sebastian's oldest church and has a richly carved retablo dating to 1584.
A favorite pastime in the Old Town is strolling the quaint cobblestone streets in search of traditional Basque tapas. This atmospheric quarter is filled with authentic pintxo restaurants and is at its liveliest in the evening, when tourists and locals flock to the area.
