What is "lactodurum"

Lactodurum was a town in the Roman province of Britannia. Today it is known as Towcester, located in the English county of Northamptonshire.

Towcester lays claim to being the oldest town in Northamptonshire and possibly, because of the antiquity of recent Iron Age finds in the town, to be one of the oldest continuously inhabited settlements in the country. There is evidence that it was settled by humans since the Mesolithic era (middle stone age). There is also evidence of Iron Age burials in the area.
