Welsh Historic Gardens Trust Award

We are delighted that we have been offered a grant to create two Knot Gardens here at Plas Tirion.

We are very grateful to have been offered support from the WHGT to create two knot gardens either side of the central path in the sloping lawns at the front of Plas Tirion. The design will be based upon the 1626 plaster overmantle in one of the downstairs rooms of the house, the strap work design lends itself perfectly to a knot garden.  The knots will be planted in an authentic Tudor fashion, with dwarf box hedges and five compartments for planting.  Over the last year we have been gradually repairing sections of the walled garden and developing the lower slope as a native wildflower meadow.  The area enclosed by these walls is being developed as an authentic Tudor garden using only plants that would have been available when the house was built.

July and August events – a festival and an exciting new course….

We are looking forward to a pleasant summer of events, with a visit to Ymuno Festival here in North Wales and a brilliant new course, learning how to colour cloth using medieval dye plants.

Over a long weekend in July, from 1st – 4th we will be visiting the Ymuno Festival in North Wales for a weekend of music, art and poetry.  We will be taking along our child-sized timber frame building with us, for willing little hands to put together and learn all about traditional buildings.  Tickets and line-up information can be found here –

And we are very excited to announce a new workshop that we are holding on 20th August.  Justine Aldersey-Willimas from The Wild Dyery will be joining us, to teach us how to dye natural fibre cloth using historic dye plants.  We will be producing a spectrum of vibrant, beautiful, natural colours using Madder, Woad and Weld, and learning how to pattern the dyed cloth with an ancient Japanese resist method called Shibori.  Please see the training section of our website for further details.

The 1498 hall house.

The end of last year saw the beginnings of the repair and study of the oldest house here at Plas Tirion, looking forward to the year ahead we have exciting plans for it.


We have here at Plas Tirion an even older house than the main Elizabethan hall.  It’s an oak cruck framed hall house dendro dated three years ago by the Discovering Old Welsh Houses group to 1498.  It may have fallen out of residential use when the main house was built, possibly acting as a domestic service building.  It has been adapted and altered over the years, with a cow Byrne and pigsty built alongside it in the C19th, but the main body of the house although now stone clad and truncated still has many early features, including the original oak cruck frame.  A local archaeological group has been excavating the floor and have made some interesting discoveries including a William and Mary coin from 1695 and the remains of an C18th grain drying kiln.  This fits in with a reference in an old letter from the 1920’s which mentions the Old Brewhouse.  The archaeological work has been rained off this winter but we hope to get back out there this month. Plans for the full restoration for the building are being drawn up, and in future it will become accommodation for our courses. When work gets underway later this year, we will be using the building as a training aid for this year’s courses, providing hands on experience of traditional building methods.
