Non- Heritage Assets Mawnan NDP
Introduction
When asked about the importance of supporting enforcement of the existing policies which protect our environment and heritage sites in Mawnan parish an overwhelming 96% of our parishioners endorsed this proposition. Then when asked to indicate which areas of Mawnan are important to them and require special protection and/or improvement 33% of respondents indicated that the whole of the parish of Mawnan is special to them and needs protection. Landscape and heritage featured strongly in the comments we have received and this has guided our listing of non- designated heritage assets of properties, sites and landscapes.
Our heritage and our history are not only present in what we can see above the ground. Features buried into the landscape are difficult to discover, catalogue and protect. The importance of the Helford River area during prehistory has become increasingly clear over recent years. Writing in 1987, the late Oliver R large population.
Mawnan is rich in Iron Age (800 BC 42 AD) and Romano-British (43 410 AD) remains. The settlement sites at Carwinon, Meudon and Carlidnack are well known, so is that of a cliff castle at Rosemullion Head a Scheduled Ancient Monument. However, further suspected sites at Penpoll, Tregarne, Trerose and Penwarne have more recently been uncovered by National Mapping Programme (NMP). Even earlier Bronze Age (2500 800 BC) activity has been established north of Meudon and at several other localities throughout the parish. Probable Neolithic (4000-ca. 2500 BC) settlements once existed at its north western fringes.
Given the broad distribution of these sites, it seems highly likely that the parish holds a large number of undiscovered settlements and burial places dating from the Stone Age to the Roman period. In order to achieve both a better understanding of the local historic environment and the protection of a fragile archaeological record, it is requested that those submitting planning applications relating to any previously undeveloped (i.e. agricultural and amenity) land provide full results of non-invasive geophysical investigations to the Parish Council before any ground disturbance is started. local distinctiveness. In addition to the 79 grade 1, 2*and 2 listed buildings in the parish there are many examples of buildings and other sites which merit some recognition for their age, local character or historical significance. We have drawn up a list comprising 100 entries which appears below. They include homes, hotels, farms, barns, walls, privies, WW2 sites, trackways, field boundaries, the stocks, water taps and a pump - an eclectic mix, chosen with reference to a variety of criteria, as follows.
Many are older properties, especially those constructed using local materials like cob, killas rubble and locally quarried stone. Others may be unique in style in this parish and are therefore locally unusual. There are also some of our most striking buildings which do not have the status of a formal listing. Other buildings are chosen because they are fine examples of the vernacular building style for this parish. Finally, in some cases the history attached to local buildings, trackways and other structures has prompted us to include them.

28 World War II (1939-45) Heritage in Mawnan Parish.
The Helford River was a place of great activity during World War II. During the early years of the conflict it was considered susceptible to enemy invasion and, as such, a great many defensive structures were erected around its shores and surrounding countryside. However, as the fortunes of Allied Forces improved it was transformed into an important site from which to deploy troops for D-Day.
The relics of both these phases are plentiful in the Parish of Mawnan. Collectively they are of immeasurable historic and educational value not only to the parish community, but nationally and internationally.
