Plas Gunter Mansion

Plas Gunter Mansion Plas Gunter Mansion & Garden in Abergavenny was built in the 17th century. It is Grade 2* but now in a terrible state of disrepair.

We are working to renovate both the building and the garden and bring them back to life. Having been neglected for many years, this important building is now owned by the not-for profit Plas Gunter Mansion Trust. Volunteers, trustees, marketers, architects and other project developers are all supporting project progression. We have received funding from Abergavenny Town Council, National Lottery H

eritage Fund, Welsh Government, National Heritage Memorial Fund, Pilgrim Trust, Archdiocese of Cardiff, and Architectural Heritage Fund. For more information on the project visit: https://www.plasguntermansion.org.uk

Two features of Plas Gunter give it a Grade 2* listing, one of them is currently in Abergavenny Museum & Castle.

It's a fresco called ‘Adoration of the Magi’ that was found on the wall of the chapel in the building in the 1900s.

This is just one of the many significant stories we tell of the history of our building and garden. Check out the others on our page!

On this day, Wednesday 27th August 1679, 347 years ago, David Lewis was executed in Usk, Wales.

But why?

In 1534, Henry VIII had taken the country away from the Catholic Faith, putting himself as the head of the church instead of the Pope. His son, Edward, was a fervent Protestant, but died young at fifteen. His sister, Mary, took the country back to the Catholic Faith again, but under Elizabeth I it was back to the Protestant Faith.

It isn't surprising that people were fearful of another change. In 1581, under the reign of Elizabeth I, a law was passed that preaching or writing to draw people away from the Church of England to the Roman Catholic faith was classed as high treason. The penalty was being hung, drawn and quartered.

This law still existed in the 1600s and in 1678 King Charles II issued a proclamation for the immediate arrest of all Catholic priests after fears had been stirred up again. Under that law, they could be prosecuted and condemned to be hung, drawn and quartered.

David Lewis secretly held mass and promoted the Catholic religion in Abergavenny and surrounding areas, including in a secret chapel on Cross Street in Abergavenny. He could not acknowledge the King as head of the church, as in his religion, the Pope was its head.

He was prosecuted for this under the Elizabethan law and executed in 1679.

David Lewis became the last Catholic martyr in Wales when he suffered the gruesome death of being hung, drawn and quartered on 27th August 1679.

A plaque in Usk graveyard marks where he was buried.

There is an archway on Beili Lane behind the building, but what is it?

It was once the course of the water channel (leat) leading from the Gavenny River.

It went across Priory Meadows to this arch by the side of the Beili Lane at the rear of the garden to Plas Gunter. The water course continued past the side of the Swan Hotel, then under the new section of Monmouth Road. It used to supply the Corn Mill on Mill Street, to add to the water power of the Cibi River.

All that is left now is the arch in the wall which went over the leat in Beili Lane.

In the picture is the arch in the wall on Beili Lane and an OS map of 1916 where the blue line shows the channel and the Gavenny river in red.

The Gunter family’s story stretches from the streets of London and Wales to the heart of Jamaica’s history. 🇯🇲

William Gunter was born in 1789 in London, the sixth child of James and Lucy Gunter. His father ran a shop on New Bond Street, and life for the Gunters was comfortable.

But William’s journey took him far from England. He moved to Jamaica, where he married Mary Morison. Together they had four children, weaving the Gunter name into the fabric of Jamaican society.

Over time, the family grew in influence both in the Caribbean and back in England. William’s descendants went on to hold respected positions, but it was his great-grandson who made history.

In 1960, Sir Geoffrey Campbell Gunter became the first Jamaican to serve as Acting Governor of Jamaica, appointed by the Queen herself. His leadership marked an important step toward greater local representation in the island’s government.

From merchants in London, to landowners in Jamaica, to one of the island’s highest offices - the Gunter family history holds a legacy.

Some major repairs and investigations have been taking place at Plas Gunter!

Our updates:
• Two treads from the original newel staircase have been removed to understand the repairs necessary.
• A major beam has twisted and turned away from the wall in the room above where our ornate plater ceiling is. Trying to put it back would result in some plaster ceiling being lost, so it is now pinned with a steel brace so it can't move anymore.
• Some internal walls have been removed to create one long space.

That’s it for now! We’ll update you with our latest activities again soon.

Thank you to The National Lottery Heritage Fund for supporting us and the National Lottery players who have made it possible. 🤞
