Lexden parish church to the left of which the Lexden Beacon rises.
The topography of the area that stretches southwards from Colchester is largely created by the rivers Colne and Blackwater and includes Mersea Island, Wivenhoe and Brightlingsea. (See Fig 1 below). Across the Blackwater estuary lies the knob-shaped promontory surrounding Bradwell-on-Sea. |

Beacon Hill, Point Clear. |
Of the two other Beacon hills in the area one is Beacon Hill, Point Clear on the foreshore closely by the village of St Osyth while the other lies across the estuary of the River Blackwater in the area called St Lawrence. In addition there is the Mersea Barrow assumed to be Roman but likely to have been raised over a much older navel position. Mersea Barrow at 51° 47.5’N 0° 55.8’E is on the same latitude as Point Clear. |
The latitudes and longitudes together with the grid references, of these three Beacon hills plus Colchester Castle are as follows:
Beacon Hill, Lexden 51° 53.4’ N 0° 51.8’E TL 972 252
Colchester Castle 51° 53.5’N 0° 54.3’E TM 000 253
Beacon Hill, St Osyth 51° 47.5’N 1°
2.3’ E TM 092 150
Beacon Hill, St Lawrence 51° 42.5’N 0° 50.8’E TL 967 050

The three Beacon Hills form an elegant pyramidal triangle whose base is 2π Grd., apothems 5 Grd and height 4 Grd. Again the pi-proportion for this figure is exact. The base is not orientated true north-south because Lexden and St Lawrence differ by one minute of longitude. The meet of the base and the height-line is marked very closely by Great Wigborough Church. The longitude interval between Lexden and Point Clear Beacons is 10.5’ which converts to 42 seconds of solar time. This echoes the 42 minute intervals found in the Plan of Egypt, (P-Z #12), the Holy Oblation (P-Z # 3) and also between the parallels spanning Silbury Hill and Warren Hill (P-Z # 4). Further we found it in the immense pyramidal triangle (of which Colchester Castle navel is the apex) that has a base stretching between St Radegund’s and Cowford . This spans 84’ of longitude. (P-Z # 13) |

The latitude intervals between Colchester Castle, Beacon Hill Point Clear and Beacon Hill St Lawrence are 6’ and 5’ respectively and the use of such proportions are mirrored by the careful placement of Mersea Barrow (below).
|
Firstly the Barrow lies on the same parallel as Point Clear and its parallel is 5’ north of that through St Lawrence.
So Mersea and St Lawrence define a small geodetic square of side five minutes. |
