Field notes
The atlas divides its material into catacombs, caves and grottoes, mines, and bunkers or underground cities, with 55 destinations visible on the homepage. Its entry format emphasizes pre-visit logistics rather than scenery alone: ticket prices, ticketing method, steps, temperature, season, and suitability for children or people with claustrophobia. Examples range from Edinburgh vaults to Icelandic ice caves and Istanbul's Basilica Cistern.
