CRISIS AT THE CASTLE follows the trials and tribulations of three of Britain's stately homes and the families who own them. While the public might assume that these historic marvels are supported by fabulously wealthy people, that is often not the case. Each of the castles profiled is at a critical point owing to the cost of upkeep and maintenance. The families battle with constant roof-leaks, falling visitor numbers, mounting debts, and often with each other. Will their hold on these amazing houses continue? The mini-series is a fascinating look at grand homes from a bygone era and the often quirky people who struggle to preserve them for future generations.
