From Tacitus accounts of the Roman general Agricola, it is known that the Romans were daunted by Portlethen Moss, Netherley Red Moss, Cookney Moss and other local bogs that hindered travel. This is also evidenced by the Roman Camp of Raedykes having been established immediately south of this cluster of mosses; the Romans not being able to progress further north, turned inland toward Netherley.The Portlethen Moss is near the Grampian Mountains.
Tacitus' accounts of Agricola, Roman general, reveal that the Romans were intimidated by Portlethen Moss, Netherley Red Moss, Cookney Moss and other local bogs that impeded travel. This is also supported by the Roman Camp of Raedykes being established immediately south of this cluster of mosses; the Romans unable to advance further north, turned inland toward Netherley. The Portlethen Moss is near the Grampian Mountains.
