Although its depiction of Mexico is heavily condensed and stylized, you can visit a lot of real-world places in "Forza Horizon 5". Here are a few highlights.
Inside the Gruesome Mummies of Guanajuato in the 1950s
The Mummies of Guanajuato are a number of naturally mummified bodies interred during a cholera outbreak around Guanajuato, Mexico in 1833.
The human bodies appear to have been disinterred between 1870 and 1958. During that time, a local tax was in place requiring a fee to be paid for “perpetual” burial. Some bodies for which the tax was not paid were disinterred, and some apparently those in the best condition were stored in a nearby building. The climate of Guanajuato provides an environment which can lead to a type of natural mummification, although scientific studies later revealed that some bodies had been at least partially embalmed.
