The manor was a seat for many centuries of the junior branch of the Basset family which gained much wealth from local tin mining.
They acquired the manor of Tehidy in the mid-12th century when William Basset married Cecilia, heiress of the House of de Dunstanville.
[2] Within the boundaries of Tehidy Country Park, evidence of man's activities can be found dating back many centuries.
In the woodland in the North Cliffs area is an ancient earthwork and in Oak Wood, earth banks that were field boundaries can still be seen.
Typical woodland plants such as Bluebells, Wild Garlic (Allium triquetrum), Daffodils and a range of native ferns inhabit the park as well as many different varieties of Rhododendron.
The park is home to, amongst others, swans, geese, rooks, jackdaws, coots, moor hens, grey squirrels, otters and badgers.
