If you love the rolling countryside of Wales, how about owning a slice of it; over 275 acres?

Now that's a decent sized garden.

But with this stunning landscaped garden with tennis court, acres of fields, pockets of ancient woodland, and stunning vistas of some of Wales' most distinctive mountains including the Skirrid and the Sugar Loaf, also comes a stunning house that oozes grandeur.

Great Campston is a property jewel nestled within the rolling rural landscape of Monmouthshire and offers the next lucky owner a picture perfect property and a wonderful place to live their best country life.

The gorgeous Grade II listed Georgian house is currently the most expensive house for sale in Wales, if you disregard any 'price on application' properties, and offers a new owner almost their own little hamlet.

There's a lake too but plenty of space for a pool if a new owner fancies one

In the grounds there is an extra two-bed guest cottage, a three-bed bungalow and an extensive range of outbuildings included in the asking price of offers in excess of £4.5m.

According to the website British listed buildings, the reason the manor is listed is because it is a "substantial 17th-century house with an early and important history".

This history includes the claim that King Charles II visited the property that was on the site in 1645, such was the regional importance of the house.

But its history actually goes further back than the royal visit - it's thought that there's been a settlement on this site since the 12th century.

It is also believed to be where the battle of Campston Hill occurred in 1404, thought to have resulted in a heavy defeat for the last native Prince of Wales, Owain Glyndwr, although definitive proof of this is hard to find.

The property has changed hands a number of times in its long history, and has undergone many renovations to the final design of the Georgian building that survives to this day.
