Rosewyn is mentioned in the Heritage England Records as a medieval settlement in 1302.  The buildings are shown on the earliest map of the area in 1699.  It is believed that the main house dates back to around 1615.  The main roof timbers are thought to be original and bear the carpenters marks.
Set in 5 areas of Cornish rural landscape the owner, who has been a Fellow of the Royal Geographical Society for nearly 40 years, specialising in geomorphology, has undertaken various projects to promote the ecology and environment at Rosewyn which include:

 - Planting over 100 endangered British hardwood trees
 - Constantly maintaining and improving trees  
 - Growing oak trees from acorns
 - Planting an orchard of rare Cornish cider and eating apples
 - Producing apple juice and cider from the crop of our own apples
 - Building and installing a Barn Owl box
 - Creating a walk around the field
 - Creating a path through the County Wildlife Site along the wooded stream
 - Using a polytunnel and allotment for growing vegetables

 - Installation of a large septic tank
 - Installing 4 LPG boilers to run from bulk LPG to reduce harmful emissions and create a more efficient heating system
 - Installing air conditioning units in outbuildings

 - Squirrels
 - Numerous songbirds
 - Magpies and Pigeons
 - Buzzards and occasionally Kestrels
 - And a magnificent Barn Owl who calls in from time to time.

And most of all: You can see the sun rise and set and because of the dark skies: the Milky Way and shooting stars.
