The Antonine Fort at Cadder

The fort on the Antonine Wall at Cadder measured about 364 ft. from east to west by 339 ft. north-south (c.111 x 103 m) enclosing an area within the ramparts of just over 2¾ acres (c.1.14 ha). The northern defences of the fort were formed by the rampart wall of the Antonine barrier, the other three sides being enclosed by a turf rampart about 15½ ft. (c.4.7 m) wide at the base. There were two ditches on the east and the south with a single ditch on the west; the outermost ditches extended outward into clavicular defences at both the eastern and southern gateways. Although the gateway through the eastern defences was placed centrally in its side, none of the other three were, that in the southern rampart being displaced noticeably to the east, while those on the western and northern sides were displaced slightly to north and east respectively.

The fort was excavated between 1929-31, during which several coins, some 1st-century glass and sherds of samian pottery were found. There have been six coins recovered from the environs of the fort; single denarii of Galba and Trajan, 2 dupondii of Antoninus Pius and 2 copper coins of uncertain minting. The pottery recovered includes pieces stamped with the names of five Antonine potters; two of Casurius Form 31, and single examples of Cinnamus Form 37, Comprinnus Form 31, Minatio Form 33 and Peculiaris Form 31.

"There were, however, two or three sherds for which an early date seemed probable, and with these may be classed a considerable portion of a Samian vessel of Form Dr. 35, which was picked up at Cadder in 1852 and whose colour and texture suggest that it is of first-century manufacture." (MacDonald, p.312)

The samian pottery and the glass finds, if accurately dated, suggest that there was a Roman presence at Cadder at some time during the 1st century, and the only conceiveable period during which this could have been acheived were the campaigns of governor Gnaeus Julius Agricola through Scotland in the early AD80's. The fragile nature of glass in particular makes it unlikely that these vessels had lasted on campaign from the late-1st century until the mid-140's before being broken.

Epigraphic Evidence from the Cadder Fort

Military Building Inscription


"A detachment from the Second Legion Augusta¹ [made this]."

(RIB 2188)

  1. The Second Augusta were normally garrisoned in the legionary fortress at Isca Silurum (Caerleon, Gwent, South Wales).

The R.I.B. records two Latin inscriptions on stone from the Antonine fort at Cadder in Kilsyth. One records the name of the legion who were responsible for the actual construction of the fort and its defences (vide RIB 2188 supra), while the other is an altarstone to a Latin god probaby dedicated by the commanding officer of one of the auxiliary regiments who garrisoned the fort (vide RIB 2187 infra). Also of note is an ansate slab with the right ansation broken-off found in 1604 at Bogton Farm, ½ miles east of the fort, now in the Hunterian Museum, Glasgow (RIB 2186 etiam infra).

Altar Dedicated to Silvanus


"To the god Silvanus, the prefect Lucius Tanicius Verus fulfills his vow, gladly, willingly and deservedly."

(RIB 2187; Britannia 1977.31; altarstone)

Building Dedication by the Second Augustan Legion


"For Imperator Caesar Titus Aelius Hadrianus Antininus Augustus Pius, father of his country, the Second Augustan Legion was responsible for three miles and six-hundred and sixty-six and a half (feet of rampart wall)."

(RIB 2186; ansate slab; dated 139-161AD; see RIB 2193 at Balmuildy)
