Why are there so many churches in Seoul?
There are a few really huge churches in South Korea, but most church-goers attend small local churches. Each church, no matter how small it may be, has a cross sign. Many churches have a cross on top of the building that lights up at night. If you are in Seoul, you may see up to ten neon cross signs when you turn around a full circle.
Some people believe that the reason churches are so successful and plentiful in Korea is because they are very profitable.
