To provide a civil engineering structure capable of providing necessary information at site even if the civil engineering structure is damaged by an accident and also provide a control system of the civil engineering structure.

In this civil engineering structure 10 comprising RF tags 12 in which the structure information on the civil engineering structure 10 can be stored, the structure information is dividedly stored in the plurality of RF tags 12 since a plurality of divided information formed by dividing the structure information are held in the RF tags 12, respectively. Each divided information is doubly stored in the plurality of RF tags.
