Our Story

Until 1290 the land at Tremenheere was owned by the monks of St Michaels' Mount. William De Tremenheere bought the land at that time, having probably already been established as a tenant farmer, beginning an lineage of 600 years where the land carried the name Tremenheere.

This persisted until 1890 with the last Tremenheere being Seymour Tremenheere. The gardens are greatly indebted to this man as it was he who planted the Beech, the Oak, the Sweet Chestnut and Holly throughout the woods in or around 1830. He essentially did the early landscaping work. As well as the tree planting, he created a carriage way which zigzagged its way up the hill to his summer retreat. Seymour Tremenheere was a prominent national figure, being First Inspector of Schools, Inspector of Mines and whilst living in London travelled to Cornwall in a yellow chariot. He created a fine cut stone entrance bridge which carries his initials and the date 1849. The land at Tremenheere was said to be the vineyard for the Mount in the 15th Century. Much later in the 1800s it was a noted strawberry growing area with products being exported to Newfoundland at that time. The land is south facing with good soil. The pH varies from 7.2 in the previously highly cultivated areas to 4.6 under the beech trees. It is early favoured land, largely sheltered from prevailing winds by the mature woodland and the particular sheltered valley landscape. A free flowing stream runs through the bottom of the valley and several substantial ponds are aligned nearby. The total area amounts to 20 acres and is situated a mile east of Penzance along a stretch of land known as the Golden Mile.

As well as the happy combination of good soil, mild microclimate and shelter, the land benefits from majestic mature tree woodland and outstanding views across the bay to St Michael's Mount.


The guiding principle has been to evolve a naturalistic, arcadian space blending the elements of landscape, planting and art to create a place for contemplation and wonder.

After the Tremenheere lineage fell away the Pearce family farmed the land for 4 generations until 1997 when Dr Neil Armstrong acquired the core valley to which other fields were added in the interim. Neil acquainted himself with the land in tackling heavily overgrown scrubby woodland with 10 foot high brambles, wild rhododendron and impenetrable swamp. Some of the open areas had been heavily colonised with bracken and fallen trees which liberally arranged themselves in the uncultivated sections.

The land however immediately announced itself as having tremendous potential with its natural assets – the habitats were varied from pond to dry, arid slopes. A planting scheme and landscape design was largely dictated by these natural features.

There was no big house which liberated him from the clumsy imposition of the driveway and allowed him to create paths to follow the natural camber of the hillsides using directional prompts and framing vistas as appropriate. The visitor now is drawn into the gardens from a modest track and is surprised to find the land opening up in a wide generously sized landscape. The first planting was of course the wind shelter breaks to the north and the east. The Pinus radiata, Quercus ilex and sundry native trees have since established themselves and within a short time have reached 30 feet or more. The steep terrain dictated the need for access tracks and these conveniently compartmentalised the garden, creating slightly different moods in different areas.

Tremenheere hopefully will add to and complement the magnificent and world class gardens of Cornwall. The strongly structural planting scheme with a sub-tropical emphasis means the gardens do not follow the traditional spring flourish but have more of an all-season interest.

Clearly the artwork and landscape retain their interest and appeal at all times of the year.

To all at Tremenheere
Just wanted to pass on to you how impressed we were with our visit over Easter. Our boys, and adults included, thoroughly enjoyed the Nature Workshop around your beautiful gardens. Fantastic day and looking forward to returning soon.
Kind regards
