The restoration work which is being carried out on Bellver Castle has unearthed further wall drawings believed to have been carried out by prisoners held in the castle in the 18th century. A council spokesman said yesterday “we have found drawings of sailing boats, crosses and shoes. Our experts say that they are at least three hundred years old. Bellver Castle was used as a military gaol housing French prisoners of war. The discovery will mean a further delay to restoration work which is being undertaken on the keep. “Naturally, the drawings must be studied and investigated,” said the spokesperson. Once the restoration is completed, with special attention being paid to the stairway, the keep will be open to the public. The view is quite breathtaking.
