 This method of construction for gates is not seen outside Scotland, although window grilles constructed in this manner are found in northern Italy and Tyrol.Grated windows in the Scottish style were traditional in Tyrol in the 15th century, and similar window grilles are seen a century later in Venice, particularly the 16th century Palazzo Ducale (although the bars are somewhat larger than those used in Scotland).It is likely the craft spread south from Tyrol to the Venetian Republic, but little apparent connection to the earlier Scottish technology, although there was some trade between Scotland and Germany.
