Celtic times

( From 5th century before J.C. to our era). Little is known about it. The natural harbour of Blavet was a part of the province of the Veneti. One might think that Caesar's famous naval battle against the Veneti, in 56 before J.C. took place near the present Port-Louis.It is indeed very likely that in this time, the place of the citadel was occupied by a "blocked spur", such as they existed on numerous capes in Brittany.
In Caesar's Gallic Wars (III, 12) one can read : "The sites of their towns were generally such that, being placed on extreme points [of land] and on promontories, they neither had an approach by land when the tide had rushed in from the main ocean, which always happens twice in the space of twelve hours; nor by ships, because, upon the tide ebbing again, the ships were likely to be dashed upon the shoals. Thus, by either circumstance, was the storming of their towns rendered difficult;"

Only in toponymy can we find traces of these primitive fortifications, as in "er goh castel" (the old castle) which until the end of the 19th century was the name given to the eastern point of Pen Mané (now a marsh), north of Kervern village. Known as the "Vieille Tranchée", which origin is lost in old times, a deep ditch would cut the isthmus of the peninsula of Port-Louis in the axis of the present rue du Port. A very active maritime business took place in the harbour of Blavet .Evidence of it appears from dredged amphoras.
This maritime activity was confirmed by Caesar himself who wrote, about the Veneti:
"The influence of this state is by far the most considerable of any of the countries on the whole sea coast, because the Veneti both have a very great number of ships, with which they have been accustomed to sail to Britain, and [thus] excel the rest in their knowledge and experience of nautical affairs; and as only a few ports lie scattered along that stormy and open sea, of which they are in possession, they hold as tributaries almost all those who are accustomed to traffic in that sea."(Gallic wars, III, 8)
