Ardotalia
Ardotalia, also known as Melandra or Melandra Castle, is a Roman fort in Gamesley, near Glossop in Derbyshire, England.
Ardotalia was constructed by Cohors Primae Frisiavonum—The First Cohort of Frisiavones. Evidence for the existence of this unit exists not only from the building stone found at the site but also from various diplomas and other Roman writings. This unit would have had around a thousand men, including the specialist craftsmen needed to perform the skilled work of building the fort.
This unit was assisted in constructing the fort by the 3rd Cohort of Bracara Augustani. These men were probably Iberian Celts from the colony of Braga in Portugal, who seem to have been attached to the Legio XX [Valeria Victrix|XX Legion Valeria Victrix] in Chester.
Whilst it is unknown which of these Cohorts manned the fort, it seems more likely that the 3rd Cohort of Bracara Augustani performed this duty, as they were from a hilly region and so were more experienced in holding terrain such as that found around Glossop. The Frisiavones were from low-lying lands beyond the Rhine and so may have been divided between the lower terrain of Manchester and Northwich.
The First Cohort of Frisiavones were also present at Brocolitia, one of Hadrian's wall forts and settlements, at Carrawburgh, Northumberland. Evidence for this relies on an inscription on an altar stone, which tells us that Optio Maus had repaid a vow to the goddess Coventina. Whether this altar was the repayment of the vow is unknown.

The name Melandra is of unknown origin but may have been originated by the John Watson, Rector of Stockport, who visited the site c. 1771 when substantial stone remains existed. The name Ardotalia is a hypothetical emendation of Zerdotalia written in the Ravenna Cosmography. The fort was excavated in the late 1800s. The towers were described by Charles Roeder: "They are built square and stand detached, 4 feet away from the angles, measuring 10 feet by 11 feet, the walls being 3 feet thick."
An excavation by Hamnett and Garstang was further described by Roeder, reporting:
The site is a Scheduled Ancient Monument., it is on the Heritage at Risk Register, its condition described as "enerally unsatisfactory with major localised problems".
Doctor's Gate is a track connecting Ardotalia and Navio fort at Brough-on-Noe. It was formerly believed to be a Roman road and signage still exists to this effect
