While in Colombia last month, I traveled an hour north from Bogotá to Zipaquirá to see the stunning Catedral del Sal (Salt Cathedral). The Salt Cathedral is a Roman Catholic church built 650ft underground within the tunnels of an abandoned salt mine. Years before the underground church was built and it was only a mine, the miners carved out a sanctuary as a place for the daily prayers to ask for protection. The cathedral has been declared the first wonder of Colombia, and rightfully so. To build the cathedral, 250,000 tons of rock salt had to be extracted.
The cathedral now serves as a functioning church that draws up to 3,000 visitors every Sunday. It has three main naves representing Jesus' birth and baptism, life and death, and resurrection. Along the naves are several altars where worshippers can pray.
