Publisher's Synopsis
This earthquake shock was the result of those which at the same time destroyed Lisbon. The Leads, used for the confinement of state prisoners, are in fact the lofts of the ducal palace, and take their name from the large plates of lead with which the roof is covered. One can only reach them through the gates of the palace, the prison buildings, or by the bridge of which I have spoken called the Bridge of Sighs. The prisons are under the roof on two sides of the palace; three to the west (mine being among the number) and four to the east. On the west the roof looks into the court of the palace, and on the east straight on to the canal called Rio di Palazzo.
