Aist River

There was a timber and earth fortrets that date, uh, fortress that dates to the first century CE, and then a stone fort that d- dates to the second century CE.

And they say together that this, these two forts likely controlled this crossing point near the river, near its confluence with another waterway, the Aist River, that was an important trade route for regions beyond the Roman Empire.

So this was a strategically important spot.

And then civilian settlements sprang up near these Roman forts, providing goods and services to the troops stationed there.
