We organised a trip to Sealyham as a team-building exercise for the company and cannot recommend them highly enough. Everything was well planned and we were all made to feel welcome by the excellent staff. Everyone agreed that it was a beneficial experience and we left feeling like a tighter-knit group.

Geoff Evans

My daughter came home from a school trip recently at Sealyham Activity Centre and was full of praise for the centre. She’s very fussy but loved the food. She’s not particularly outdoorsy but tried everything on offer and said the instructors were amazing and helpful. She said the rooms were spacious and comfortable.

Our History

Sealyham Mansion, a Georgian Country House, the estate consists of 100 acres of seclued woodland and the river Anghof, a tributary of the Western Cleddau, runs though the grounds.

Humble Beginnings

King Edward III granted some land at Sealyham, to Thomas Tucker in the fourteenth century. Tucker was a captain in the King’s army about 1356. From that time “The Tuckers of Sealyham” remained identified with the manor until 1777.Though Tucker signifies a fuller of cloth, there is a tradition that the first Tucker had accompanied William the Conqueror in 1066 to England.

John Tucker Edwards

Known for the creation of the Sealyham Terrier there in the 1800s. John Edwards bred the Sealyham Terrier rare Welsh breed dog. It turned out the last of the descendant family members to live at the Sealyham Mansion was Mrs Catherine Octavia Edwards. She married Victor James Higgon. In 1905, they moved to Treffgarne Hall. Around 1910, portions of the land were sold to the Pembrokeshire County

New Property Built

Tucker married Ursula del Holme and they built a house at this Sealyham property, which is some 200 miles (320 km) southwest of Liverpool. The house was rebuilt in the mid-18th century.The local slate quarries were developed by the family, yet they struggled despite advisor’s having been brought in from North Wales to make improvements and eventually they were closed down.

Old Sealyham Mansion

In 1920, Sealyham Mansion and its immediate associated land were sold to the King Edward VII Welsh National Memorial Association. The estate was converted into a tuberculosis hosptal with 30 beds, from 1923 to 1954. In 1955 it was converted for geriatric patients and but in 1964 it was permanently closed as a medical facility.

Sealyham Saboteurs

During the war years Sealyhams woods played host to a special army sabotage unit nicknamed the “Sealyham Saboteurs”. The 6 man patrol was equipped with explosives and trained in sabotage techniques in case of invasion. The unit, lead by Captain Tommy George of the Harp Inn at Letterston regularly practised raids on local British and American bases and the airfield at Withybush

New Ownership

In 1970, the Sealyham Mansion was sold to Nancy Ellen Perkins. She converted it into an apartment building as rentals. In 1980, it was sold again to an investment firm that used it for an outdoor activities centre.</p> <p>On the 29th September 1986 Sam & Valerie Richards and John and Peggy Hone purchased Sealyham and the Woods and have been improving the house, grounds and activities ever since.
