The Salt Church of Colombia is located 50 km north of Bogota and is one of Colombia's famous tourist destinations. The town is beautiful and the river is clear. In the 1990s, the local government closed the salt mine for safety reasons. In fact, it was originally used by miners to pray for blessings while working underground, and then continued to expand until now to a dizzying degree. And also applied for the eighth wonder of the world, but did not finalize. The cathedral is below 180 meters above the surface, which is spectacular.
