**Wales’ Priciest Property on the Market for £15m is a Surprising Slice of Eryri (Snowdonia) History**
Wales is no stranger to attention-grabbing properties, but the current most expensive listing in the country is truly in a league of its own. On sale for a staggering £15 million, the property in question is not a palatial mansion or futuristic development, but a significant portion of the iconic Nannau Estate in Eryri (Snowdonia) National Park. This sale represents a rare chance to acquire a breathtaking expanse of Welsh countryside, woven with history and brimming with opportunity.
Nestled in the hills above the Afon Mawddach, the Nannau Estate encompasses nearly 3,800 acres of diverse landscape. The territory spans mature woodland, lush pastures, rocky grazing uplands and a network of fresh streams—all situated within one of the nation’s most celebrated and picturesque regions. These features combine to offer an extraordinary rural retreat and a unique investment prospect.
For those seeking both heritage and business potential, Nannau is already home to a thriving mixed-use operation. The current owners have expertly balanced large-scale farming and forestry, holiday letting businesses, and residential property management, creating a sustainable estate that combines tradition with modern diversification. There are three holiday cottages on offer, all finished to a very high standard, alongside eight other residential properties and three working farms. Such a blend provides an established income as well as room for further development.
Notably, the estate’s environmental value is considerable. Several Sites of Special Scientific Interest (SSSIs) are dotted throughout, protecting waterways, peatland and woodland. These acknowledged habitats create excellent opportunities for buyers focused on conservation, biodiversity, and the delivery of ecological benefits. The balance of commercial, residential and environmental assets is rare for a property of this scale and prominence coming to the Welsh market.
The estate also offers scope for the sporting enthusiast, with extensive woodland providing ample stalking and shooting options. Additionally, a desirable stretch of the Afon Mawddach river falls within the estate, offering further recreational and sporting potential. For those with an eye to expanding operations, an extra 498 acres could become available in 2027, promising further opportunity for forward-thinking investors.
At the heart of the estate, history buffs will find much to admire. Amongst characterful buildings is the Hywel Sele Lodge, believed to have been erected between 1794 and 1818 and functioning as the northern gateway to the ancient deer park. Built in a semi-ruinous Tudor-Gothic style, it stands in testament to the estate’s long association with Welsh heritage. Coed y Moch Lodge, the southern entrance, is another notable structure—Grade II listed and rooted in the area’s woodland history, its Welsh name referencing the pigs that once roamed the oak forests.
The nearest town, Dolgellau, sits just under a mile southwest of Nannau. Known locally as the town of “music and mountains”, Dolgellau is the largest settlement within the national park and caters for residents and visitors alike, with independent shops, cafes and key amenities. The town also acts as a hub for the surrounding agricultural community, enhancing the commercial appeal of the estate.
It is rare indeed for such an eclectic and historical holding to be listed on the open market. With its blend of productive agricultural land, established holiday business, potential for increased tourism and sport, and environmental credentials, Nannau is much more than just a swathe of stunning Welsh countryside. It is, without doubt, a once-in-a-generation opportunity for those able to meet its considerable price tag.
The estate is being marketed by Savills Rural Sales, with interested parties encouraged to make enquiries for further details. Whether as a commercial venture, a conservation project, or a historic family seat, Nannau offers a unique slice of Wales that is sure to captivate—and perhaps surprise—even the most seasoned property watchers.
