Bollingen, a village of a few houses, lies within the canton of Saint Gallen at the shallow upper end of the Lake of Zurich, about twenty-five miles east of Kusnacht, the Zurich suburb where C. G. Jung had his home. Another mile eastward, on the edge of the reedy water, Jung bought a piece of land in 1922 and set to building a house. From a quarry near the village he got the raw stones; and, working with two stonemasons from nearby, he learned to split, dress, and place them himself. In 1923 he finished a tower of two stories. At intervals over twelve years he built an annex, another tower, and a loggia.
