hi listchecker

for a trained eye and the acquired knowledge it will be enough to just look at the building materials to know approximately how old they are. many criteria will play a role in determining the age, whether it is the environmental influence of past years or the overall development about which one knows through scientific reports. i also think that a lot is analyzed in laboratories.

best regards.oobravo
