The St. Gimmel Chapel draws inspiration from the Italian legend of the "double-ring". Encircled by a 500-kilogram crystal installation that shimmers like entwined rings under the sun, it symbolizes the eternal bond of love. Floor-to-ceiling glass immerses the chapel in Karuizawa's seasonal beauty, from verdant summers to crimson autumns. A wooden altar beneath a luminous dome bathes each ceremony in natural light, as if blessed by the forest itself.
