Carrawburgh is a settlement in Northumberland. In Roman times, it was the site of a 3½ acre (1.5 ha) auxiliary fort on Hadrian's Wall called Brocolitia, Procolita, or Brocolita This name is probably based on the Celtic name for the place, and one possible translation put forward is 'badger holes'. The fort there was a mile or so west of the Wall's northernmost point at Limestone Corner, and just over a mile west of the nearest milecastle, Milecastle 30. The fort either used the Wall (narrow gauge on a broad base at this point) itself as its northern rampart, or was built parallel to it but detached. It certainly postdates both the Wall and the vallum (which it is built across).
Only the fort's earthworks are now visible, the Wall at this point and the fort's north ramparts having been demolished for the construction of General Wade's early 18th-century military road (now the B6318). The late 19th-century archaeologist John Clayton carried out a partial excavation of the site, revealing a military bath-house outside the fort's west gate (in 1873) and the fort's south-west corner-tower (in 1876).
The Roman Inscriptions of Britain lists 48 inscriptions for the site. They show its garrisoning units to have been as follows:
- RIB 1550 – Hadrianic? – First Cohort of Aquitani
- RIB 1563b – AD122-138 – First Cohort of Tungri
- End 2nd century – Cohors I Cugernorum
- RIB 1544, RIB 1553, and Notitia Dignitarum – AD213-222? and AD237 respectively – First Cohort of Batavians
The First Cohort of Frisiavones are also attested at Brocolitia at some stage, as shown by an inscription on an altar stone, which tells us that Optio Maus had repaid a vow to the goddess Coventina. (This unit is also recorded as present at Ardotalia.) Whether this altar was the repayment of the vow is unknown.
The remains of three Roman sanctuaries have been discovered in the low-lying marshy ground beyond the fort's south-west corner. All three sites lie adjacent to a small tributary stream of Meggie's Dene Burn, which runs three miles from Carrawburgh to empty into the River South Tyne near Newbrough's fort on the Stanegate.
Nearest to the fort, about 80 metres from its south-west corner, are the remains of an early 3rd century mithraeum, i.e. a temple of the mystery cult of the Roman god Mithras. Discovered in 1949 and excavated by I.A. Richmond and J.P. Gillam in 1950, it is the second-most northernly mithraeum discovered so far (only Bremenium, a few miles from Brocolitia, is further north).:282:77 The Procolitia mithraeum is also the only sanctuary outside the Rhine provinces from which a monument of the goddess Vagdavercustis has been recovered. Like most other mithraea, the Brocolitia temple was built to resemble a cave, and also had the usual anteroom, and a nave with raised benches (podia) along the sides.
At Procolitia, the anteroom and nave were separated by a wattle-work screen, the base of which was found exceptionally well preserved. Excavations revealed three stages of development::292–293 the first stage was small, around 5.5 metres wide and 8 metres long.:79 The building was expanded to 11 metres length in a second stage, at which time the temple also gained elaborate furnishings and extensive woodwork. This second stage existed for the entire 3rd century, and included at least two major renovations. The second stage was looted and the furnishings destroyed around 296–297 AD, but the sanctuary itself and the stone monuments remained intact, and the temple was re-equipped in a third stage shortly thereafter. The third stage includes three monuments by different cohort prefects, commanders of Cohors I Batavorum, a Roman Batavi unit of auxiliary cavalry stationed at Brocolitia.:79 All three date to the 3rd century.:79 The youngest coin found on the premises was a freshly-minted follis of Maximian (r. 296–308).:296 This coincides with the third structural period on Hadrian's Wall (297–367), but the complete lack of coins from after 308 suggests that the temple did not remain in use for much of the 4th century.:296 The temple was deliberately desecrated by the removal of the primary tauroctony scene, only a piece of which was found. Other than a collapsed roof, the temple was found almost exactly as the Romans had left it. The foundations of the temple are still visible, as are the wooden stakes on which the podia benches were raised. A reconstruction of the sanctuary is on display at Newcastle University's Great North Museum.
Behind the mithraeum are the remains of a nymphaeum, which was found in 1957 and excavated in 1960. The third site was a "Coventina Well", a centre for worship of the Romano-British goddess Coventina. This sanctuary, discovered by Clayton in 1876, is the source of the stream. No remains of the nymphaeum or well are now visible.
- The name "Procolita" is found in the 5th-century document Notitia Dignitatum, and "Brocoliti" in the 7th-century Ravenna Cosmography. In both instances it appears between the entries for Chesters (Cilurnum/Celunnum) and Housesteads(Borcovicium/Velurtion).
