1798 - napoleonic wars
John Of Gaunt’s cellar is thought to have been used as a prison during the Napoleonic Wars.
Elaborate, deeply cut graffiti can still be seen in the cellar from this period. James Thompson's account of Leicester Castle, published in 1859, describes John of Gaunt’s cellar as a “long, dark and damp chamber, the sides and roof of which are constructed of wrought stones. It is fifty feet from end to end, eighteen feet wide, and twelve feet high from the original floor, now covered over with accumulated earth and rubbish."
