If it was built with spoils from the Temple, I suppose that means that nothing much likely survives from the Temple. I recall Prof. Steven Fine pointing out that very little gold or other precious metal (apart from burial sites) survives from ancient times, as it’s very easy to melt down and reshape, and they didn’t care much for antiquities’ value as such back then- so no more Menorah, etc. (He also pointed out that while there are records of a scroll of Torah being brought with the spoils, scrolls don’t survive except in very dry climates.)
