Milecastle 33 was a milecastle of the RomanHadrian's Wall, one of a series of small fortlets built at intervals of approximately one Roman mile along the length of the UNESCO World Heritage Site in northern England. Its remains exist as clearly visible earthworks, with the exception of part of the north gate and wall, and a fragment of the south gate, which are exposed. Exposed parts survive to a maximum height of . The remains are located a few metres to the north of the B6318 Military Road.
Construction
Milecastle 33 was a long-axis milecastle with Type II gateways. Such milecastles were thought to have been constructed by the legio XX Valeria Victrix who were based in Deva Victrix. The external dimensions of the milecastle are by, and the large, monolithic threshold installed is of the same type installed in milecastles 13, 17, and 53.
Excavations and investigations
1930 - A fragment of ornamented stone with a distinct pattern of leaves is found at the North gate.
1935-6 - The milecastle is excavated, and the dimensions and remaining structure established.
1966 - English Heritage Field Investigation. The 1935-6 findings were reconfirmed.
1988 - English Heritage Field Investigation as part of the Hadrian's Wall Project. It was noted that the maximum height of surviving masonry was. Other previous findings are reconfirmed.
Associated Turrets
Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 33 are known as Turret 33A and Turret 33B.
Turret 33A
Located in 1920, nothing now remains of Turret 33A, due to extensive stone robbing. Its position was stated by Eric Birley in 1961 as "150 yds. east of the twenty-seventh milestone at the bridge crossing the Coesike". Location on Ordnance Survey 1:25 000 map:
Turret 33B
Turret 33B is located approximately west of the point where the wall line and the B6318 Military Road diverge. It has been exposed, and consolidated to a maximum height of. In plan, the turret has an entrance to the east end of the south wall, with a platform in the south-west corner, and a hearth at the centre. The walls are thick. It was built with broadwing walls of Standard A, which join to a narrow gauge wall at this reach. Material used for the blocking of the rear recess mentioned below included an inscribed stone naming the legio VI Victrix. This suggests that this legion were responsible for the original construction. There is evidence that the following changes occurred during occupation:
The hearth was replaced twice
The floor was raised and part-flagged
The threshold of the door was lifted
The turret was abandoned, and reoccupied following withdrawal from the Antonine Wall
The door was blocked at the end of the second century, when the turret apparently went out of use.
Subsequently, the turret was demolished down to four courses and the recess in the rear of the wall blocked up.
Occupation evidence includes jars and cooking pots, butchered remains of young animals, and the dumping of ashes from the hearth outside the east wall. Location on Ordnance Survey 1:25 000 map:
