At around 5am, at least two thieves used ladders to scale the walls of Levens Hall, near Kendal before climbing to a first floor room. It is understood that the clock was damaged during the burglary and one of its four feet is now missing.
South Cumbria police have also released an image of the bronze and ivory figure of Napoleon on horseback by E.B. Masson which was also stolen in the burglary.
