te parenga o Belfort, i te teitei o te 425 m. I hangaia te Fort des Basses Perches o tenei wa i runga i tenei papaanga, na te mea i kitea he waahanga nui o nga paruru o te tonga o Belfort i te Pakanga Franco-Prussian. Ko te pourewa tata tapawhā he mea rongonui mo te whakamahinga wawe o nga countercarps i te waahi o nga caponiers, i rongonui ake a tae noa ki tera wa.
