Las Mumias.
There was a cemetary in Guanajuato, that for some reason they needed to move, but when they uncovered to bodies, many of them had been preserved into mummies. If the families could not pay to have their relatives replaced in the new cemetary, the government got to keep the bodies, and they made a whole museum with these mummies, most still with hair and clothes. They could tell how they died and when. This woman was buried pregnant, and her fetus is displayed beside her. Pretty neat, and a little creepy.
