Ailsa Craig (//; Scottish Gaelic: Creag Ealasaid) is an island of 219.69 acres in the outer Firth of Clyde, 10 miles from mainland Scotland, upon-which blue hone granite was quarried to make curling stones. The now uninhabited island is formed from the volcanic plug of an extinct volcano.
The island, colloquially known as "Paddy's milestone", was a haven for Catholics during the Scottish Reformation in the 16th century, but is today a bird sanctuary, providing a home for huge numbers of gannets and an increasing number of puffins.
The island is owned by The 8th Marquess of Ailsa, but since May 2011 has been up for sale. By March 2013 the asking price was for offers over £1,500,000, down from the original asking price of £2,500,000.
An early reference to the rock is made by Sir Donald Monro, Archdeacon of the Isles who referred to the rock as "Elsay" in the 16th century. The modern name of the island is an anglicisation of the Gaelic, Aillse Creag meaning "fairy rock". An alternative Gaelic name is Creag Ealasaid meaning "Elizabeth's rock". The first element, Aillse may represent Allt Shasann, "cliff of the English", mentioned in the Book of Leinster as Aldasain.
The island is sometimes known as "Paddy's Milestone", being approximately the halfway point of the sea journey from Belfast to Glasgow, a traditional route of emigration for many Irish labourers coming to Scotland to seek work.

- Creag Alasdair: "Alasdair's rock"
- Ealasaid a' Chuain: "Elizabeth of the ocean"
- Carraig Alasdair: "Alasdair's Rock" (used in the Madness of Sweeney, the tale of a legendary king of Ireland).
Geography and geology
The island, which is located approximately 10 miles (16 km) west of Girvan, is 2 mi (3.2 km) in circumference and rises to a height of 338 m (1,109 ft).
Geologically Ailsa Craig is the remains of a volcanic plug from an extinct volcano. It stands out because all younger sedimentary rocks covering Southwest Scotland have long since been eroded away. But the island survived erosion because it is composed of much harder igneous rocks from the Palaeogene era (65,000,000 years ago). The plug, which is composed of granite, is all that remains from the massive volcanic activity which accompanied the continental drift that formed the Atlantic Ocean. Dykes of similar age can be found in Scotland through other older rocks such as the extensive Cleveland and Eskdalemuir dykes. Though only a few metres across, these volcanic dykes can be traced all the way from northern England back to an ancient supervolcano on the Isle of Mull.
Research has shown that the granite on Ailsa Craig has an unusual crystalline composition that has a distinctive appearance but a uniform hardness. These properties has made the island's rock a great favourite material for curling stones.
The only surviving buildings on the island is its lighthouse on its east coast facing the Scottish mainland, and a ruined towerhouse, that was built by Clan Hamilton to protect the area from King Felipe II of Spain in the 16th century.
In 1590 the shipping of the Clyde was disrupted by pirates who were said to be Highlanders, quha lyis about Ailsay.
Ailsa Craig was a haven for Roman Catholics during the Scottish Reformation. In 1597 the Catholic supporter Hugh Barclay of Ladyland took possession of Ailsa Craig, which he was intent on using as a provisioning and stopping off point for a Spanish invasion which would re-establish the Catholic faith in Scotland. He was discovered by The Rev. Andrew Knox, a Protestant minister (who later became both Lord Bishop of the Isles and Lord Bishop of Raphoe). Barclay thereafter either tried to escape or deliberately drowned himself in the sea off Ailsa Craig.
The island was used as a prison during the 18th-19th century.
The lighthouse was automated in 1990 and converted to solar electric power in 2001; the island has been uninhabited since automation in 1990. Ailsa Craig and its lighthouse feature extensively in Peter Hill's book Stargazing: Memoirs of a Young Lighthouse Keeper. Though quarry blasting is no longer allowed, loose granite rock from the island has been recently used for manufacture into curling stones by the Kays of Scotland company. The island is now a bird sanctuary, leased by the RSPB until 2050. Huge numbers of gannets nest here and following a pioneering technique to eradicate the island's imported population of rats a growing number of puffins are choosing to return to the Craig from nearby Glunimore and Sheep Islands.
An annual hunt of the solan geese or gannets took place in the days of Robert Burns as the flesh was considered a delicacy. Robert Burns' maternal uncle, Samuel Burns was involved in the solan goose trade.
The island has a fresh water spring but no electricity, gas, sewage or telephone connections. The island currently belongs to The 8th Marquess of Ailsa. In May 2011 it was announced that the island was for sale; originally given an asking price of £2,500,000, as of March 2013, the current asking price is for offers over £1,500,000.
From the mid-19th the island has been quarried for its rare type of micro-granite with riebeckite (known as "Ailsite") which is used to make stones for the sport of curling. As of 2004, 60 to 70% of all curling stones in use were made from granite from the island  and is one of only two sources for all stones in the sport, the other being the Trefor Granite Quarry in Wales.
Ailsa Craig produces two types of granite for curling, Blue Hone and Ailsa Craig Common Green. Blue Hone has very low water absorption, which prevents the action of repeatedly freezing water from eroding the stone. Ailsa Craig Common Green is a lesser quality granite than Blue Hone. In the past, most curling stones were made from Blue Hone but the quarry is restricted by environmental conditions that exclude blasting.
Kays of Scotland has been making curling stones since 1851 and has the exclusive rights to the Ailsa Craig granite, granted by the Marquess of Ailsa. The last "harvest" of Ailsa Craig granite by Kays took place in 2013, after a hiatus of 11 years; 2,000 tons were harvested, sufficient to fill anticipated orders through at least 2020.
