Perhaps the smallest museum I’ve ever been to. Located in Hyehwa, this lock museum has a small and unique collection of locks from around Korea and different countries in the world. This is perhaps not your typical tourist destination. It’s for anyone who is interested in locks and/or those who are in the area and want to find something a little different to check out for about ten minutes for the price of 3000won. To get here, come out of exit 2, walk straight and turn left before the building with the Dunkin Donuts. Walk straight and you will come to a pretty interesting building on the right that’s across from a mural.
