The Parish of Langton Matravers contains 2,215
acres of land. Originally it was larger, but in boundary changes of 1933
it lost a neck of over 1,000 acres stretching eastwards into what is now
the Parish of Swanage.
The parish is situated in the south-east of the
Isle of Purbeck, between the parishes of Swanage and Worth Matravers.
A
line of 'Celtic' or pre-Saxon fields along the north side of the present
village High Street proves that this settlement was sited at its present
location before the Roman Conquest and before the Christian Era. The outlying
settlements of Acton, Blacklands Coombe and Knitson have been proved by
archaeological finds to be of similar antiquity.
There are six named streams within the parish, though their names do not appear on the Ordnance Survey maps. In order of size they are: La Trencheye (which flows in a trench along the clay vale to reach the sea beside the Mowlem in Swanage, where it is called The Brook); the three tributaries of La Trencheye, Knaveswell from the north and Puck Lake and Gully from the south (all three of which have given names to settlements); Broadwathe and Severallwathe, which, together with some unnamed small streams, run southwards and over the cliff into the sea. There were formerly many ponds in this parish, of which some ten are still in existence.
