The Kazan spring is the oldest of all the Diveevo springs. It appeared in July 1579 during the reign of Ivan the Terrible, after the appearance of the icon of the Mother of God in Kazan. According to tradition, the Queen of Heaven appeared three times at this site. Until the 20th century, a large chapel with a marble iconostasis and beautifully painted icons stood above the spring. Two of them, depicting Saint Nicholas and the Venerable Sergius of Radonezh, are now in the Trinity Cathedral of the monastery. In the 1930s, one of the residents of Diveevo found an ancient icon of the Kazan Mother of God under the ice of the frozen spring. Three years later, the chapel was destroyed, but in 1943 the icon miraculously renewed itself. It is now kept in the Trinity Cathedral of the Seraphimo-Diveevo Monastery in the chapel dedicated to the icon of the Mother of God "Tenderness." Old-timers recall that the chapel was tall, with many icons on the walls, and in the center was a log cabin spring from which a stream flowed. Sick children were bathed here, and water was taken for ablution. In 1991, a chapel and bathing area were built again over the spring, where the sacrament of baptism is now performed. In the early 21st century, two more springs were arranged and consecrated near the Kazan spring: in honor of the Great Martyr Panteleimon and in honor of the icon of the Mother of God "Tenderness."
