Trematon Castle Gardens

A perfect miniature Normal Mott and Bailey Castle, Gatehouse built for Edward the Black Prince in 1350. With astonishing views of the Tamar Estuary and a new and very ‘Flowery’ garden, only five minutes from the A38.

Trematon Castle has belonged to the Duke of Cornwall since soon after the Norman Conquest. Built on the ruins of an earlier Roman Fort it survives, a perfect miniature Norman castle, motte and bailey with a gatehouse built to be fit as lodgings for Edward, Prince of Wales, known as the ‘Black Prince’. When Sir Francis Drake returned to Plymouth from his circumnavigation voyage in 1580, he slipped out to anchor behind St Nicholas Island until word came from Queen Elizabeth for the treasures he had gathered to be stored in Trematon Castle.

In 2012, garden designers Julian and Isabel Bannerman moved in and began to plant a garden which is intended to play to the Castle’s romantic and pre-Raphaelite glories, the astonishing wild flowers, woodland and orchard, have been intensified with bold borders full of scent, colour, lustre and panache.

There is mixed woodland with dogwood and magnolia, tulip tree, foxglove tree, evergreen oaks and oaks. At the end of April the Motte is a riot of wild flowers, carpeted with cowslips and primroses, bursting with bluebells, spangled with campion and purple orchids, and in the summer flushed with ferns and scented with wild thyme, majoram and woodbine.


Follow the A38 through the Saltash tunnel and over the Saltash services roundabout and continue into Cornwall. Take the third left signed ‘Trematon’ and ‘Trehan’, turn left at t-junction, then bear left at fork for ‘Longlands’ and ‘Trehan’. Trematon Castle is 1/2 a mile further along on the left hand side the Car Park will be clearly indicated on the left coming from Trematon and Trehan before the Castle Lodge and Entrance Gate. If you are coming from the Forder direction it will be found on the right, after the Castle Entrance and Lodge.

But for the benefit of local residence and not overly congesting the narrow lanes it is requested that you approach from Trematon and Trehan as directed and leave via Forder, St Stephens and Saltash.
