It become an important centre whence Roman roads branched out in all directions.[3] It was an administrative, military and commercial city located close to the Seine. This made it a great transportation route betweenBritannia (modern-day Britain) and the remainder of theRoman Empire. It was also a crossroads of communication for Roman roads toHarfleur,Étretat,Dieppe,Évreux andRouen. The city was completely destroyed in the middle of the 2nd century.
The remains ofRoman baths and of atheatre capable of holding 3,000 persons have been brought to light.[3] Many Roman relics, notably abronzestatue ofApollo (displayed in theLouvre) have been found. The importantLillebonne mosaic, well preserved and depicting a deer hunt, comes from a suburban villa and is on display at the Rouen Museum. It was made by T. SEN FILIX fromPozzuoli, Italy and AMOR, his local apprentice.
It was again ruined in thebarbarian invasions of 273 after which the theatre was made into a fortress: the exits were blocked, wells were dug, and baths put up in the arena.
In theMiddle Ages the town walls were constructed out of materials from the Roman theatre. The town recovered some of its importance underWilliam the Conqueror.[3]
Lillebonne is the birthplace of the writerAnnie Ernaux.

TheGallo-Romanamphitheatre of Lillebonne was built in the first century, and was altered in the second century so that it could be used as both an amphitheatre and atheatre. Part of its remains are still visible today from Félix Faur Square, and the foundations of some of its remnants (the wings and backdrop) remain under the square.
The principal industries in the past werecotton-spinning and the manufacture ofcalico andcandles.[3] There was also a prosperous manufacture of starch belonging to theLegrain family.
