Strange Places: The Salt Cathedrals of Colombia

Deep beneath the mountains of central Colombia lies one of the world’s most unusual religious structures — a cathedral carved entirely from salt. Known as the Salt Cathedral of Zipaquirá, this underground church is located inside a former salt mine about 180–200 meters below the surface, turning an industrial space into a breathtaking spiritual and architectural wonder. 0

An Underground World of Salt

The cathedral sits inside a massive halite (rock salt) deposit near the town of Zipaquirá, north of Bogotá. Salt has been mined here since at least the 5th century BCE by the indigenous Muisca people, making the region one of South America’s oldest salt-producing areas. 1

When visitors enter the cathedral, they descend through dimly lit tunnels carved directly into the salt rock. Along the path are 14 small chapels representing the Stations of the Cross, each featuring a cross and prayer space carved from the surrounding mineral walls. 2

From Miners’ Chapel to Architectural Wonder

The idea for the underground sanctuary began in the 1930s when miners carved a small chapel in the tunnels to pray for protection before starting work each day. 3

In 1954, a larger cathedral was officially opened inside the mine. However, ongoing mining operations weakened the structure, forcing authorities to close it in 1992 due to safety concerns. 4

Rather than abandoning the site, engineers and architects designed a new cathedral deeper in the mountain. The modern version opened in 1995 after removing roughly 250,000 tons of salt to create stable underground chambers. 5

The Cathedral’s Interior

Inside the cavernous sanctuary, visitors encounter massive columns, sculptures, and altars carved directly into salt rock. The cathedral’s layout contains three main naves symbolizing the birth, life, and resurrection of Jesus. 6

One of the most striking features is a gigantic illuminated cross carved into the rock at the end of the main chamber. Artistic lighting highlights the crystalline salt walls, giving the cathedral an almost surreal glow that changes color as visitors move through the tunnels.

Today, the Salt Cathedral is both a functioning church and one of Colombia’s most famous tourist attractions, drawing hundreds of thousands of visitors each year. 7

More Than a Church

The cathedral is part of a larger complex called Salt Park, which includes museums, geological exhibits, and educational displays about mining and natural resources. The surrounding tunnels showcase sculptures and artworks carved by local artists and miners. 8

While many churches inspire awe through towering architecture above ground, the Salt Cathedral of Colombia does the opposite. Hidden deep inside a mountain of salt, it proves that some of the world’s most remarkable places are found far below the surface.
