Muiryfold was one of the Roman fortifications built by Septimius Severus in northern Caledonia (modern-day Scotland).

The site was discovered by aerial photography in 1959, and two small trenches were excavated across the north west and south east sides by Kenneth St Joseph the same year.

[1] The camp was almost rectangular, measuring 784 metres (2,572 ft) from north west to south east, and 522 metres (1,713 ft) from north east to south west, covering an area of just over 41 hectares (100 acres).

[1] In 210 AD, the Emperor Septimius Severus made an attempt to conquer all Caledonia reaching the Moray Firth.

The Roman legions in the first and second century established a chain of very large forts at Ardoch, Strageath, Inchtuthil, Battledykes, Stracathro and Raedykes,[6] taking the Elsick Mounth on the way to Normandykes before going north to Glenmailen and possibly Bellie.
