Vindolanda was a Roman auxiliary fort (castrum) just south of Hadrian's Wall in northern England, which it pre-dated. Archaeological excavations of the site show it was under Roman occupation from roughly 85 AD to 370 AD.

It is noted for the Vindolanda tablets, a set of wooden leaf-tablets that were, at the time of their discovery, the oldest surviving handwritten documents in Britain. Early accounts.
