Gesoriacum

Etymology
The Morini tribe held this coastal settlement in early Roman times. This Gaulish or Belgic tribe was identified as being the Gessoriaco Morinorum gentis by the Venerable Bede. The name of the settlement was changed from Gesoriacum [spear-fort place?] to Bononia possibly in honour of Bornonia, a Celtic divinity, at some stage between the sack of Gesoriacum and the year 310 AD.
