List of Orkney islands facts for kids
The Orkney Islands are a group of islands located off the northern coast of Scotland. This amazing archipelago (which means a group of islands) is about 16 kilometers (10 miles) north of mainland Scotland. There are over 70 islands and small rocky islets called skerries in Orkney. About 20 of these islands have people living on them all the time.
The biggest island is called the Orkney Mainland. The other islands are grouped into the North Isles (north of Mainland) and the South Isles (south of Mainland). There are also the Pentland Skerries, which are tiny islands in the Pentland Firth. This area has very strong ocean currents. The Island of Stroma is sometimes thought to be part of Orkney, but it actually belongs to Caithness.
An island is defined as land surrounded by seawater every day, even if it's only at certain times of the tide. This definition does not include land connected by human-made bridges or causeways. Four islands in Orkney are linked to the Mainland by special causeways called the Churchill Barriers. These islands are South Ronaldsay, Burray, Lamb Holm, and Glimps Holm. Also, Hunda is connected to Burray by a causeway.
The Churchill Barriers were built during World War II by Italian prisoners-of-war. They were made to protect Scapa Flow, a large natural harbor, from enemy submarines. This was important after a German U-boat sank a British ship, HMS Royal Oak, in 1939. The Italian prisoners built a small Roman Catholic chapel on Lamb Holm. It was a place for them to worship while they were there.
Most of the Orkney islands are made of Old Red Sandstone. This rock is about 400 million years old! The islands have good land for farming and have been lived on for thousands of years. You can see this at the World Heritage Site called the Heart of Neolithic Orkney, which has ancient stone buildings. Because the islands are windy and have strong tides, there are many lighthouses to help ships navigate. The European Marine Energy Centre in Stromness is testing new ways to get energy from waves and tidal energy from the ocean. All the islands are part of the Orkney Islands Council. Many of the larger islands have groups that help support the local economy.
The total number of people living in Orkney grew from 19,245 in 2001 to 21,349 in 2011.
Discovering the Main Islands of Orkney

This section lists the islands of Orkney that are larger than 15 hectares (about 37 acres). We don't have full records for when the smaller, uninhabited islands were last lived on. However, all the islands listed here were likely home to people at some point in history. This includes the Neolithic (New Stone Age), Pictish, or Norse times.
Many islands have a highest point called 'Ward Hill' or a similar name. These places were used to light warning beacons long ago.
