The appearance of the Guanajuato Tunnels several centuries ago was due to the channel of the Guanajuato River running under the city, resulting in constant flooding during the rainy season. To avoid this, the first water channels appeared, which were distinguished by a unique engineering character. Guanajuato has more than 8 kilometers of underground streets spread over 23 tunnels, each telling its own story and keeping secrets or legends to discover.
