Zipaquirá's stunning Catedral de Sal is one of the country's most unique attractions, carved by meticulously removing 250,000 tons of salt and flipping the resulting space into a gorgeous underground Roman Catholic church, cinematically lit and packing a whole lot of ecclesiastical wow throughout its cavernous chapels and naves. Admission includes Parque de la Sal attractions like a light show, 3D film, brine museum and other imminently skippable distractions.
All visitors must join regularly departing groups on hour-long tours – you can leave them once you're inside if you want. The walk leads past 14 stages of Jesus' fateful day, with hollowed-out crosses symbolizing nakedness or death; the illuminated cupola; and, finally, the stunning nave. The tradition of mixing religion with salt has logical roots: work in the mines was dangerous so altars were made. The 75m-long mine can accommodate 8400 people and holds services on (very busy) Sundays, though lacking a bishop, it has no official status as a cathedral in Catholicism.
