Tower of London

The Tower of London is an ancient fortress on the Thames’ north bank, a grim medieval stronghold of thick stone walls and iron-barred windows that has housed kings’ tempers, prisoners’ chains, and the echoes of executions. Within its dank cells, captives like Sir Walter Raleigh endured isolation, their murmurs and the clink of chains soaking into the very masonry. The Doctor first encountered the Tower during a quarrel with Henry VIII over a cut of meat called the 'parson's nose,' parking the TARDIS inside to dodge Tudor guards. Later, he recalled these stone walls to Jo while both were confined elsewhere, using the memory of Raleigh’s solitude to articulate a weary, immortal perspective on his own captivity. By the time of his fourth incarnation, the Tower had become just another landmark on the Thames’ north bank, its specific history and hauntings receding into the fabric of London itself.
