The earliest reference to this fort and settlement beside the River Lune is in Ptolemy's Geography of the second century, where the name Calatum appears among the towns of the Brigantes tribe between the entries for CATARACTONIVM (Catterick, North Yorkshire) and ISVRIVM (Aldborough, North Yorkshire), which was the tribal civitas capital.
The town also appears in Iter X of the Antonine Itinerary "The route from Glannoventa (Ravenglass in Cumbria) to Mediolanum (Whitchurch in Shropshire)", this time listed as Calacum, 19 (Roman) miles from ALAVANA (Watercrook, Cumbria) and 27 miles from BREMETENACVM (Ribchester, Lancashire).
The etymology of the Roman name may stem from the Latin word calathus, 'wicker basket, flower basket; wine-cup; cheese-making vessel', perhaps in reference to its superb location in the Lune Valley, which would certainly be strewn with meadow flowers from spring through autumn, and would have been excellent cattle-raising country - as it still is today. This is not substantiated by further evidence, however. The modern name stems from the Old English word Burgh, meaning 'the fortified place', and is first mentioned in the Domesday Book of 1086.
The fort lies on a slight prominence almost ½-mile (0.6 km) east of the River Lune, beside the A638 road from Kirkby Lonsdale to Lancaster. The plateau occupied by the fort and its annexes measures about 830 ft. by 330 ft. (250 x 100 m), covering an area of about 6¼ acres (c.2.5 ha) aligned roughly NNE-SSW. This is sufficient space to have easily housed an ala quingenaria, a five-hundred strong unit of auxiliary cavalry,. However, excavations conducted on the site in 1952/52 seemed to indicate that the fort itself occupied the southern end of the platform, and was almost square in outline measuring about 470 ft. by 445 ft. (143 x 135 m) enclosing about 4¾ acres (1.94 ha), which is enough space for a cohors peditata milliaria, a one-thousand strong auxiliary infantry unit.
As of 1985 there were 30 Roman coins recovered from Burrow-in-Lonsdale, ranging from Vespasian (69-79AD) to Constantius I (305-306AD). The silver coins identified are of Trajan (RIC 49ff; Imp. 98-117AD) and Sabina (RIC 413a; c.117AD?), identified bronzes are of Hadrian (RIC 974; Imp. 117-138) and Commodus (RIC 645; Imp. 180-192). Of all these coins, 13 are Antonine, which may be indicative of a re-occupation in strength during this period. There are no 3rd century coins, and only 2 tetrarchic issues of the 4th, both GENIO POPVLI ROMANI issues of Constantius I.
The evidence seems to suggest that the Roman fort at Calacum underwent at least two periods of occupation, where perhaps an original Trajanic cavalry garrison were replaced during the Antonine period by a large infantry unit, with a military presence being maintained until the 4th century at least.
No latin inscriptions are listed in the RIB for Casterton or Burrow in Lonsdale, but several have been found at Overburrow, beside the Roman road south of the fort at Casterton. None of the inscriptions can be dated and none are of definite military origin, though indeed, some of the finds testify to there being a civilian settlement here. Out of the eight stones reported in the RIB only four are reproduced on this page, including all of the altars; the others texts are too fragmentary to provide any useful data.

A Roman milestone found 4 miles north of Kirkby Lonsdale at Hawking Hall in Cumbria (RIB 2283), reads simply M P LIII 'fifty-three thousand paces' or 53 Roman miles, which corresponds quite favourably with the measured distance to Luguvalium (Carlisle, Cumbria). This milestone is particularly interesting, as it may mark the spot where Iter X of the Antonine Itinerary branches off the main north-south route and heads off across the southern Lake District past the fort at Alavana (Watercrook, Cumbria) to its northern terminus at Glannoventa (Ravenglass, Cumbria).
Another inscribed Roman milestone was found on the line of the road between Burrow-in-Lonsdale and Lancaster, 8 miles to the south-west at Caton.
