Biggest Cities of Europe in 700 AD with a Map

Albeit, these were definitely its final years and it was limited to a smaller area than before (from to 130 ha to 40 ha). With the Muslim takeover of Crete a century later, power fully shifted to Chandax (Heraklion).

The same goes for Gortyna, which occupied a smaller area than before and was essentially in decay by this time period (from 119 ha, of unknown size after), but still served as the capital for the Eastern Roman theme of Crete.

Austrian Vienna at the time was going through spelling shifts with Germanic languages becoming more prominent in the region, e.g. 'Weniam', although it would still often be referred to through the Latin Roman-era name of 'Vindobona'.

Later on, Ipswich (Gipeswic) and Southampton (Hamwic) both would decline to a population of about 1,000 - 2,000 by 1000 AD, while London (Lundenwic) would've already moved back to within its ancient Roman walls and abandon the (at the time) newer '-wic' settlement, creating the settlement of Lundenburh instead.

York (Eoforwic) is also sometimes considered part of list due to its '-wic' suffix, although it actually continued to grow with the revival of European towns around the turn of the 11th century.
