Coquelles, La Cimenterie, Stp Bremen - What is it ?

[Stp Leo]

Hello everyone,

On the June, 12th 2019 I went at the Stp Bremen at la Cimenterie, Coquelles (where there is the tunnel for the 24 cm Theodor Bruno). I discovered a strange building at the west of the place, in front of a big barrack... What is it ? It is a circle :
