Pen Dinas (Aberystwyth)

Heading north leaving the upper fort, there is a break in the ramparts where a stone-walled isthmus gate stood as high as a two-storey building and was crossed by a wooden bridge supported on four massive timber posts to link the two parts of the fort. Today heavy vegetation covered everything. See Coflein for more information and photos of previous excavations -
