A unique manor house near Helston has come on the market for £1.35 million but few may realise how historical it is.

Trenethick Barton was mentioned in a Country Life Article in April, 1961, as being a Tudor farmhouse, but Trenethick can trace its history back to Domesday when the manor was held by the king.

The present day 15th Century fortified manor house is Grade 1 Listed and acknowledged as being of national importance. It is approached through double oak doors between a granite archway below an ancient barbican.

The property has been the subject of much restoration work in recent years and is now a comfortable family house of considerable interest.

The accommodation briefly comprises six reception rooms, seven bedrooms and three bathrooms. There is also a separate three bedroom cottage.

A Grade II Listed coach house also exists. The grounds extend to about 2.92 acres and include a wonderful enclosed courtyard to the front of the house. Historically, at the Domesday inquest in 109, Helston was still held by the king. This would have included Trenethick, then spelt Trevenetheke.

During Norman and into the medieval period, the manor was the home of the Seneschall family and Walter Seneschall was a member of parliament in 1377.

In 1392 the house, through his widow Margery, was assigned to the Hill family who took the Seneschall coat of arms which can still be seen on the front door to the house and on the gatehouse.

The Hills were successful tinners and re-built the house as a stronghold for their valuables and legal documents. The current house was largely built by the Hill family in the 15th century and extended in the 17th, 18th and 19th centuries.

The gatehouse was built as a semi-defensive building as part of a planned great house and was probably occupied by a guard in times of unrest.

The property is one of the most interesting 16th century buildings in the county.
