Westmeston  Westmeston is a village and civil parish in the Lewes District of East Sussex, England heavily dependent in amenities on larger Ditchling to the near-immediate northwest. It is four miles (6 km) south-southeast of Burgess Hill and (10 km) west of Lewes, on the northern slopes of the South Downs. The parish church is close to a populous crossroads and dedicated to St Martin. Of modest size it dates, with much restoration and addition, from the 12th and 14th centuries. The nave was built soon after 1100, and the original north doorway remains. The ecclesiastical parish is today united with Streat and Ditchling. Clayton to Offham Escarpment is a Site of Special Scientific Interest, which stretches from Hassocks in the west and passes through many parishes including Westmeston, to Lewes in the east. The site is of biological importance due to its rare chalk grassland habitat along with its woodland and scrub.
