[00:00.000]In fact, this room is just theatre. [00:02.720]The canopy has echoes of a medieval lord's Great Hall. [00:07.602]Dotted around are chairs from previous coronations, [00:10.809]each one belonging to a different monarch. [00:12.853]And then framing the whole thing [00:14.636]is this fabulously ornate arch, [00:18.657]complete with winged Victories holding up swags and medallions. [00:23.060]It's like something you might find framing a West End stage. [00:27.143]Today, it's hard to imagine this spot as it was 500 years ago. [00:31.752]Back then, it was no more than a quiet backwater, [00:35.277]regularly flooded by a river, now long forgotten, the Tyburn River. [00:42.111]Hidden deep beneath the crowded streets, the river still flows.
