The camp marked was one of the many supposed "Caesar's Camps", also called Schapsbury Hill and Shasbury Hill, a square, Early Iron Age, British (not Roman) fort site of c. 500 BC, south of Bath Road, about halfway between Heathrow Road and Hatton Road, and a bit north of due east of Heathrow Hall. It was about (90 m) square (c. 1820 measurement) or (120 m) square (1911 measurement). It survived because it was on common land until the enclosure of the Commons of Harmondsworth parish in 1819, after which the fort's ramparts were mostly and fairly quickly ploughed out.

It was excavated hurriedly in 1944: see timeline in the article on Heathrow (hamlet). Inside its rampart 15 circular hut sites were found, and a large rectangular building which was probably a temple. The east end of the north runway obliterated it.

Red (arterial)

• Bath Road: the quite straight, east-west road. Note the slight fork formed by the 1926-built Colnbrook (and Longford) by-pass.

Yellow (non-arterial)

• Cain's Lane: northeast of the aerodrome. It ran 1950 metres. Its south end stays as a suburban street in New Bedfont and opposite the Great South West Road for 150 metres as a Heathrow internal minor vehicle track. A farming family was associated with it including Isaac Cane or Cain. On Enclosure of the Commons into farmland in 1819, he was awarded land to found Cain's Farm.
• High Tree Lane: narrow lane west of the aerodrome. It ran 630 metres to a ford and footbridge over the Duke of Northumberland's River.
  • That ford officially was called Goathouse Tree Ford, but the local people called the ford area High Tree River/Ford.
• Goathouse Road: runs 770 metres south from that ford into Long Lane (West Bedfont, Stanwell). May have been named after an enclosure called Goathouse Close which was in the area before.
• Heathrow Road: runs south past Heathrow Hall former farmstead, then turns west forking in Perry Oaks farm. A narrow yard east of The Three Magpies pub (into its car park) is a narrowed remnant of its north end: see Google Earth map link. It briefly dates to the era of road numbering, namely as the B379.
• Hatton Road: the road at a \-type angle to the right of the word CAMP and running to Hatton. Its ends exist now (see this Google Earth map). Vestiges persist: partly-overgrown tarmac and (as on Google Earth's files at 3 January 2012); a crop mark on grass at the east end of the north runway; alignments of airport service buildings; the south part of the airport internal road Eastchurch Road.
• Tithe Barn Lane: road from Perry Oaks almost due north.
• Oaks Road: road from Perry Oaks southward. A bit of its south end survives in Stanwell. Once part of the B379 road.

White (tracks)

• Long Lane (Heathrow): lane or track leading west from Tithe Barn Lane then north to the Bath Road at the edge of Longford.
