Wawel Cathedral’s main gate is at the west end. You will first encounter Trinity Chapel (Queen Sophia’s Chapel) on the left and the Chapel of the Holy Cross (Jagiellon Chapel) on the right. Soaring above them is the Clock Tower. Although construction began in the late 14th century, Wieża Zegarowa was not finished until 1522. The dome was added in 1715. The tower has been fitted with four versions of the Great Clock … in 1519, 1602, 1681 and the current one in 1899. You will enjoy hearing the gong every quarter hour. Also notice the brick Silver Bell’s Tower. Wieża Srebrnych Dzwonów may seem less significant based on size. Yet sections date back to the early 1100s, qualifying it as the cathedral’s oldest tower.
