"Danfeng Gate" of the Daming Palace (China)

Year 663 (DCLXIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. The denomination 663 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

Emperor Constans II launches an assault against the Duchy of Benevento (Southern Italy). Taking advantage of the fact that Lombard king Grimoald I is engaged against Frankish forces from Neustria, Constans disembarks at Taranto and besieges Lucera and Benevento.
Constans II visits Rome for twelve days—the only emperor to set foot in Rome for two centuries—and is received with great honor by pope Vitalian. Constans gives the order to strip buildings, including the Pantheon, of their ornaments to be carried back to Constantinople.
Constans II moves the imperial court from Constantinople to Syracuse. He tries to stop the Arab conquest of Sicily and restores Rome as seat of the Byzantine Empire. Constans strips sacred altar vessels from churches all over Rome.
May 8 – Battle of Forino: The Byzantine army led by Constans II is defeated by the Lombards under Romuald I. He seizes Taranto and Brindisi, receiving military aid from the Bulgar Alcek horde who are settled in the area of Ravenna.

King Oswiu of Northumbria invades Pictland (modern Scotland). He establishes overlordship of, at least, the Southern Pictish sub-kingdoms of Fortriu and Fib (and possibly Circinn).
A brief outbreak of plague hits Britain (approximate date).

June 5 – In China, the Daming Palace becomes the government seat and royal residence of emperor Gao Zong of the Tang Dynasty.
Battle of Baekgang: Korean Baekje forces and their Japanese allies are defeated in a naval battle by a joint Silla–Tang coalition.
