Church of the Holy Comforter in Vienna has a permanent outdoor labyrinth. The labyrinth, a memorial gift, is patterned after the ancient labyrinth at Chartres Cathedral in France. The labyrinth is open to the public. All are invited to experience the blessing of silent prayer as they walk in this quiet setting. Four guided walks are scheduled for the summer as an introduction to the labyrinth. Weather permitting; the first walk will be Wednesday evening, June 25, from 6:30 to 8 p.m. The other two walks will be held on Wednesday, July 23 and Wednesday, Aug. 20 from 6:30 to 8 p.m.
