[00:03.270]This is the River Tyburn. [00:05.036]And now it's channelled through this great Victorian sewer, [00:08.916]but it still follows its ancient course, [00:11.245]right beneath Buckingham Palace. [00:13.926]And it provides a fascinating glimpse into the past, [00:17.229]because this river made the land above boggy and marshy, [00:22.379]with pools of smelly, stagnant water. [00:26.555]Not exactly what you'd call prime royal real estate. [00:30.459]Until one king decided it might be useful after all. [00:37.758]Henry VIII, who came to the throne in 1509, [00:41.164]was a man passionate about the chase, for women and deer. [00:50.468]For Henry, [00:51.080]the swampy land on the banks of the river Tyburn was perfect for hunting.
