Seoul is turning Friday night into a cultural scavenger hunt, linking downtown exhibitions, hands-on activities and performances in a walking tour that invites visitors to explore the city one stamp at a time. The Seoul Metropolitan Government will pilot “Stamp Your Way Through Culture” on Nov. 6, connecting Seoul Gallery, Sejong Story, Chungmugong Story and Garden of Gratitude before participants choose between a craft performance and a literary reading. The tour is part of “Culture Night, Culture Bit by Bit,” a city program that runs every Friday evening from 6 p.m. to 9 p.m. at eight cultural venues from April through December. Applications open Wednesday through Seoul’s public service reservation system, with places available for 50 participants on a first-come, first-served basis. The tour begins at 3 p.m. at Seoul Gallery, in the basement of Seoul City Hall, where participants can explore an exhibition marking the centennial of the creation of Korean Hangul braille and make business cards bearing their names in braille. Starting at 4 p.m., participants can visit Sejong Sto
