Treago Castle is a fortified manor house in the parish of St Weonards, Herefordshire, England (). Built c. 1500, it was recorded as a Grade I listed building on 30 April 1986—based on its extant medieval architecture, quadrangle courtyard layout and defensive wall corner towers. Digging on the site revealed solid bedrock, conflicting rumours of a previously filled moat. Main building The building was probably built by Sir Richard Mynors (c. 1440–1528 ), a tax collector in Wales. The name originates from "Tre" (homestead or farm) and "Ago" ( being the Welsh form of the name "James"), suggesting there was a previous dwelling on the land. The fortified house was built to keep the Welsh out, but was never under attack. Originally the building was of a secure design, featuring a central courtyard and no externally facing windows. Later, the courtyard area in the centre of the building was covered over in stages and new windows added to the outside walls, forming a more traditional house. Mason's marks matching those at Raglan Castle and traced to William Herbert, 1st Earl of Pembroke, were detected following a visit in 1975 by the Chief Inspector of Ancient Monuments, A. J. Taylor. There are similarities to Croft Castle, also in Herefordshire. Whilst Treago Castle remains a private family home, wine tasting sessions and local charity events allow the public a limited opportunity to view inside the castle. Estate and gardens Surrounding the main buildings is parkland, probably landscaped during the late 18th century. There is no indication of a moat, although early plans of the estate do show a leat following the contour line across the estate, to the adjacent Furnace Farm. The parkland grounds became neglected for a period between the 1790s and 1840s. Four major improvements were constructed after c. 1840: Walled garden near the road, separated from the house by a shrubbery collection named The Wilderness. Walled kitchen garden furnished with well stocked fruit trees, on the site of the modern-day vineyard and to the south of the house. Tudor/Italianate styled garden containing gravel paths, grass, flower beds and clipped Irish yew trees. Referred to as Treago Garden on tithe maps from the period. A long driveway, forming a new principal entrance to the property approaching from the east. Since 1991, the roses planted in the grounds have been primarily David C. H. Austin English roses.
