A Private Scottish Island With a Ruined Castle Is Up for Sale—for Just $7.5 Million

If you’ve ever dreamed of owning your own island — complete with a ruined castle and panoramic sea views — now might be your chance.

Shuna Island, a stunning 1,100-acre private island off Scotland’s west coast, is on the market for the first time in 80 years. Listed at £5.5 million (about $7.5 million USD), the island is being sold through estate agents Knight Frank and Sotheby’s International Realty.

According to Tom Stewart-Moore, a partner at Knight Frank in Edinburgh, while private Scottish islands occasionally hit the market, Shuna stands out for its scale, beauty, and accessibility.

“It feels like something of scale,” Stewart-Moore told CNN. “This certainly stands above the rest.”

Not Just Remote—Remarkably Reachable

Unlike many ultra-exclusive private islands that are hard to reach, Shuna is surprisingly accessible. It’s just a 30-minute helicopter ride from Glasgow Airport, making it a feasible retreat for those seeking both seclusion and convenience.

“It is very accessible — that is actually very key,” said Stewart-Moore.

What You Get for $7.5 Million

Shuna Island is more than just postcard-perfect scenery. It currently hosts eight residential buildings, seven of which are holiday rentals — offering an immediate opportunity for income generation or future development.

But the real centerpiece is its ruined early 20th-century castle, originally built by New Zealand soldier and adventurer George Buckley, a former owner of the island. While the castle is currently in ruins, its clifftop position offers spectacular views and serious potential.

“The castle is in an unbelievable position,” Stewart-Moore said. “The views really are breathtaking.”
He also noted the ruins could potentially be redeveloped into a principal residence, subject to planning approval.

The island is a natural wonderland, featuring native woodlands, open parkland, rocky coastlines, sandy beaches, and rolling hills offering panoramic views in every direction.

Who’s Buying?

Stewart-Moore sees two main types of buyers:

1. Lifestyle seekers looking for a unique, ultra-private retreat — a true “trophy asset.”
2. Investors or developers interested in ecotourism, luxury holiday lets, or sporting retreats.

“The opportunities are relatively wide on this one,” Stewart-Moore said.

And interest has been swift. Though the listing has only been live for a short time, inquiries are already pouring in from potential buyers around the world.

A Rare Opportunity in the Hebrides

With its rich history, jaw-dropping landscapes, and development potential, Shuna Island represents a rare blend of natural beauty and investment opportunity. Whether you’re drawn by the romantic notion of castle ownership or envision a high-end eco-resort, this quiet island in the Scottish Hebrides could be your real-world fantasy.
