At the foot of a chalk mountain on the bank of the Tuskary River, near the fence tower of the Znamensky Monastery, there was a well. According to legend, St. Theodosius of Pechersk used its water to prepare prosphora. In the 19th and early 20th centuries, townspeople drew water here, especially for making artificial mineral waters and pickling cucumbers. Above the spring stood a stone rotunda, which fell into disrepair and collapsed in the 1870s. In 1890, a wooden chapel on a stone foundation was built in its place, thanks to private donations and city funds. It had a niche for drawing water and was designed with elements of ancient Russian wooden architecture. The carved octagon, open like a gazebo, was topped with a cross-shaped roof with a cornice and a tall spire with a finial and keel-shaped icons. The chapel was demolished in the 1920s.
