Garo Nalbandian

Today, one descends by stairway to the Gihon Spring, from the present level of the Kidron Valley. The entrance was originally formed by a sinkhole (an erosion shaft created by water percolating through easily dissolved, carbonate rock). A remnant of the upper part of the chimney-shaped sinkhole appears in the ceiling of the passage, above the gated entrance to the spring.
