Northern Isles

geography Maturity 5-7 Next article →

The Northern Isles are an archipelago located off the north coast of the Scottish mainland.

This group consists of two primary island chains: Orkney and Shetland. The islands are situated between the Norwegian Sea to the north and west, and the North Sea to the south and east. While they are part of Scotland, they possess distinct local cultures and a shared history. The archipelago contains 36 inhabited islands in total. Orkney includes 20 inhabited islands, while Shetland contains 16. This geography makes the islands a unique maritime region within the British Isles.

The geological foundations of the two groups are very different. Orkney is largely composed of Old Red Sandstone from the Middle Devonian age.

This sandstone rests upon much older metamorphic rocks known as the Moine series. You can see this relationship on the Orkney Mainland between Stromness and Inganess. Some volcanic rocks, like Middle Devonian basalt, are also found on Hoy, Deerness, and Shapinsay. In contrast, Shetland's geology is extremely complex with many faults and fold axes. It serves as a northern outpost for the Caledonian orogeny. Some areas, like Unst and Fetlar, contain ultrabasic ophiolite, peridotite, and gabbro. These rocks are actually remnants of the ancient Iapetus Ocean floor.

The climate of the Northern Isles is cool and temperate. It remains remarkably mild for such a northern latitude due to the surrounding seas and the Gulf Stream. However, the weather is often defined by its wind. Orkney experiences an average of 52 hours of gales every year. Shetland uses these persistent winds for renewable energy. The Burradale wind farm in Shetland once set a world record for capacity in 2005.

Rainfall is significant, averaging 1,150 mm in Orkney and 1,100 mm in Shetland. Interestingly, the islands experience a "simmer dim" during the long summer days.

History has shaped the islands through various cultural shifts. They share a common Pictish and Norse heritage. For a long time, the Northern Isles were part of the Kingdom of Norway. They were eventually absorbed into the Kingdom of Scotland during the 15th century. The Norse influence remains visible in local folklore and island names.

During the 20th century, the islands also served a significant naval role during the world wars. This history of movement and conflict has left a lasting mark on the local identity.

The islands are famous for their incredible prehistoric remains. Orkney is home to the Heart of Neolithic Orkney, a UNESCO World Heritage Site.

This site includes famous locations like Skara Brae, Maes Howe, the Stones of Stenness, and the Ring of Brodgar. On the island of Papa Westray, the Knap of Howar is likely the oldest preserved house in northern Europe. Shetland is also rich in history, containing over 5,000 archaeological sites. One of the most famous is the Broch of Mousa.

A broch is a distinctive round stone tower from the Iron Age.

Economic life on the islands varies between the two main groups. Orkney features fertile agricultural land. Its largest island, the Mainland, is the sixth largest island in Scotland. In 2001, Orkney had a population of 19,245, with Kirkwall as its largest town. Shetland's economy is more dependent on fishing and the oil wealth found in the surrounding seas.

The capital of Shetland is Lerwick, which has a population of approximately 7,500. About half of Shetland's 22,000 residents live within 10 km of Lerwick. Both archipelagos are now developing their own renewable energy industries.

Today, the Northern Isles remain connected to mainland Scotland through regular air and ferry services.

Tourism is a vital part of the economy for both Orkney and Shetland. Visitors are often drawn to the prehistoric ruins and the unique natural landscapes. The islands represent a complex intersection of geology, ancient history, and modern maritime industry. They continue to be a significant part of the Scottish landscape and culture.
