Explications:
1) The engineers discovered a mummified cat sealed into the walls .
2) I think that they were stunned by the discovery because before the discovery there was already a mythique tough about the building with the black cats and the broomsticks .
3) The discovery was made by water engineers who were on a construction project.
4) its a real scientific discovery.
5) The comparison with Pompeii and the discovery is because the cat and Pompeii, are both still in good conditions , its mummified . They both were very well preserved.
Voilaaa !!!
