San Vicente Church is the city's oldest standing monument, having withstood all the historic upheaval that has destroyed San Sebastian on various occasions. Construction on this church began either the late 15th century or the early 16th century, and it's built in Guipuzcoan Gothic style. The temple consists of three naves and a cross aisle. Over time, more features were added or changed, such as the baroque entranceway (1619), the stairway to the choir (1784), the tower (1856), and the four large rose windows (1929). The church was restored, recovering the impressive appearance it boasted at its construction. Mass times: 9:30a, 10:30a, 11:30a, 12:30p, 8:30p.
