Freelander 1 Towbar and a brick wall

Hi There,

my wife hit a brick wall behind the parking slot this morning while parking backwards. As I have a towbar I was wondering where it's fitted? I think it's the rear subframe, but am not sure. It was more or less idle just re-parking straight but a loud hit. An ideas what to look out for? I think I have one of those?

It’s attached by bolts to the body shell, all double skinned to give rigidity to body shell, I doubt you’ll find any damage, the actual noise will always sound worse
