Up on one of the jagged cliff edges overlooking the Eastern coast of Northeast Auridon on top of the cliff edge is an Ayleid ruin that I don't think I was supposed to be able to access (but in my determination reached as I was taking some epic screenshots) that seemed to have walls missing and I could walk underneath the mesh.
I know this was probably placed as a scenic piece and was not meant to be viewed up close, but thought I would submit it here anyways.
