Pontoon bridge in 638. The army of the Umayyad Caliphate built a pontoon bridge over the Bosporus in 717 during the Siege of Constantinople (717–718). The Carolingian army of Charlemagne constructed a portable pontoon bridge of anchored boats bound together and used it to cross the Danube during campaigns against the Avar Khaganate in the 790s. Charlemagne's army built two fortified pontoon bridges across the Elbe in 789 during a campaign against the Slavic Veleti. The German army of Otto the Great employed three pontoon bridges, made from pre-fabricated materials, to rapidly cross the Recknitz river at the Battle on the Raxa
Luzzu while at sea. On 30 October 1948, a luzzu that was being used as a Gozo ferry capsized and sunk off Ħondoq ir-Rummien, Gozo. 23 people were killed. The town of Marsaxlokk is especially famous for the large numbers of luzzu and similar craft operating in its harbour. The luzzu is often considered as a symbol of Malta. Some luzzi have been converted to passenger carriers for tourists although the vast majority continue to be used as fishing vessels. A "kajjik" is similar in appearance and function to the luzzu, but has a square transom instead of a double-ended hull.
