Highlights

​​

Brodick Castle (National Trust)

At the foot of Goat Fell, Brodick Castle is one of Arran’s most iconic landmarks and a treasure trove of history and horticulture. Originally a medieval fortress, it was transformed into a grand Victorian residence, with significant extensions made by Princess Marie of Baden, Duchess of Hamilton, in the 19th century. Today, the castle is renowned for its world-class rhododendron collection, with over 600 species blooming across its woodland gardens. Inside, visitors can explore an impressive array of artworks, antique furniture, and silverware, reflecting centuries of aristocratic life.

​

Lochranza Castle

​Lochranza Castle is a striking 13th-century ruin perched on a narrow spit of land at the head of Loch Ranza in the north of Arran. Originally built as a fortified hall house, it played a role in Scotland’s medieval power struggles and is believed to have been used by Robert the Bruce during his campaign to reclaim the Scottish throne. Over the centuries, it passed through the hands of various noble families and was later used as a hunting lodge. Today, its dramatic setting surrounded by mountains and overlooking the sea makes it a favourite spot for photographers. Lochranza is also a greatspot to see red deer which can often be seen grazing in or near the village.

Arran Heritage Museum (Museum Website)

Arran Heritage Museum offers a glimpse into the island’s rich and varied history. Housed in a former school building, the museum features exhibits covering everything from prehistoric Arran to the modern day, with special focus on crofting, farming, and island life. Visitors can explore artefacts, photographs, and reconstructions that bring to life Arran’s social history, including the impact of the Highland Clearances and the rise of tourism. The museum also includes a recreated 19th-century cottage, a blacksmith’s forge, and a garden showcasing traditional plants.

​

Kilbride Chapel, Lamlash (Trove)

​The ruins of Kilbride Chapel are a quiet and evocative site that offers visitors a window into Arran’s medieval religious life. Dating back to at least the 14th century, the chapel served as a parish church for the eastern side of the island and features remnants of its original stonework, including a medieval piscina and aumbry. The surrounding graveyard holds centuries of local history, with memorials to stewards and workers from nearby Brodick Castle. ​​​

Twentieth Century

​

​The 20th century saw the Isle of Arran blossom into one of Scotland’s most beloved holiday destinations. With its dramatic landscapes, charming villages, and easy access from the mainland, Arran became a favourite escape for both working-class Glaswegians and the British elite.

​

For many Glaswegians, Fair Fortnight (the traditional two-week summer holiday) meant one thing: heading “doon the watter” to Arran. From the early 1900s, Clyde steamers like the Glen Sannox and Caledonia ferried thousands of families to Brodick, Lamlash, and Whiting Bay. The island’s piers bustled with activity as visitors arrived for fresh air, sea bathing, and a break from city life. Charabancs (early motor coaches) took tourists on scenic drives around the island, and local guesthouses and boarding houses flourished. Arran’s beaches, golf courses, and walking trails became summer staples for generations of Scottish families.

​

While Arran was a haven for working-class holidaymakers, it also attracted more fashionable visitors. The early 20th century saw the island become a retreat for artists, writers, and politicians. The gardens at Brodick Castle, expanded with exotic plants brought back by Edwardian plant hunters, became a symbol of Arran’s genteel appeal. The castle itself, once a medieval fortress, was transformed into a Victorian hunting lodge and summer residence for the Dukes of Hamilton.

​

Arran’s charm extended to the political elite. Harold Macmillan, British Prime Minister from 1957 to 1963, had family roots on the island. His grandfather, Daniel MacMillan, was born on Arran in 1813 and went on to co-found the publishing house Macmillan & Co. Macmillan’s connection to the island was a point of pride, and he remained linked to its legacy throughout his life. Another notable figure was H.H. Asquith, Prime Minister from 1908 to 1916. His wife, Margot Asquith, died in Lamlash in 1945, and the family had long-standing ties to the area. Their presence added to Arran’s reputation as a place of quiet retreat for those at the heart of British political life.

​

Victorian Era

​

As the 19th century progressed, the island began to reinvent itself. Small-scale industries like slate quarrying, salt production, and baryte mining emerged, while improved transport links—especially the arrival of steamers and the Ardrossan railway—opened Arran up to Victorian holidaymakers. With its dramatic scenery and fresh sea air, Arran became a fashionable retreat, and tourism quickly grew into a vital part of island life.

​

Clearances​

​

Arran was deeply affected by the Highland Clearances in the early 19th century, driven by the Hamilton family’s push for more profitable sheep farming. In 1829 alone, around 700 people were evicted when 27 small farms were merged into one. Many displaced islanders emigrated to Canada, forming lasting communities in Quebec and New Brunswick. Villages like Old Catacol were abandoned, and traditional Gaelic-speaking crofting life began to disappear. The Clearances reshaped Arran’s population, landscape, and cultural identity, leaving a legacy still remembered in both Scotland and across the Atlantic.

The Clearances Monument in Lamlash commemorates 86 islanders who were forced to emigrate to Canada in 1829.

​

The Birth of Scottish Tourism

​

The 18th century saw the beginnings of Scottish tourism with writers including Thomas Pennant, James Boswell and Dr Samuel Johnson publishing influential books describing their travels. In June 1774, Thomas Pennant visited the Isle of Arran as part of his journey documented in "A Tour in Scotland, and Voyage to the Hebrides". Over four days, he explored key sites that still draw visitors today—climbing Goat Fell, observing a basking shark in Lochranza, visiting Brodick Castle, and walking through Glencloy and the ancient stone circles of Machrie Moor. He also noted the striking presence of Holy Island and the legendary King’s Cave, later associated with Robert the Bruce. Pennant’s vivid descriptions helped introduce Arran’s dramatic landscapes and rich history to a wider audience, laying the groundwork for the island’s emergence as a travel destination. His writings, alongside those of James Boswell and Dr Johnson, played a crucial role in transforming Scotland’s image and sparking the early wave of cultural tourism that would flourish in the Victorian era.​

​

Early Modern

​

Between the 16th and 18th centuries, Arran was shaped by shifting political power and landownership, most notably under the influence of the Hamilton family, who acquired the island in the 1500s. As Dukes of Hamilton, they held vast estates and played a central role in the island’s governance and economy. During this period, Arran saw the decline of clan-based society and the rise of estate management, with Brodick Castle becoming a symbol of aristocratic control. The island’s strategic location in the Firth of Clyde also meant it was occasionally drawn into wider conflicts, including tensions during the Wars of the Three Kingdoms. While agriculture remained the backbone of island life, the early modern era laid the groundwork for the social and economic shifts that would follow in the 19th century—including the Clearances and the rise of tourism.

​

Middle Ages

​

In the early medieval period, Arran was part of the Gaelic kingdom of Dál Riata, linking it culturally and politically to both western Scotland and northeastern Ireland. By the 9th century, the island had fallen under Norse control, becoming part of the Kingdom of the Isles. The Battle of Largs in 1263 marked the decline of Norse dominance, and by 1266, Arran was formally absorbed into the Kingdom of Scotland. 

Arran’s strategic location made it a target for fortification. Three surviving castles on the island date back to the medieval period:

• Brodick Castle, originally built in the 13th century, became a key stronghold during Scotland’s wars of independence. It was captured by Edward I of England, then retaken by James Douglas in 1307 on behalf of Robert the Bruce. The castle endured further attacks in 1406, 1455, and 1544, reflecting Arran’s turbulent role in national politics

• Lochranza Castle, also dating to the 13th century, sits on a spit of land in the north of the island. It may have served as a landing point for Robert the Bruce in 1306 during his return from Ireland.

• Kildonan Castle, though less accessible today, was built after the collapse of Norse rule and guarded the southern coast against invaders

.

Viking Era

​

During the Viking era, the Isle of Arran was part of the Norse Kingdom of Norway. Viking influence is evident in local place names like Brodick (“Broad Bay”), Goatfell (“Goat Mountain”), and Kiskadale ("Valley of the Boxes") derived from Old Norse.

​​

Key archaeological sites include Kings Cross Point, where a Viking grave was excavated in 1909 containing human remains, decorated whalebone, iron boat rivets, and a coin from Archbishop Wigmund of York (c. 831–854 AD). Dun Fionn, a hill fort with later timber structures, may also reflect Viking or post-Viking occupation. Holy Isle, known for early Christian monasticism, remained significant during the Viking period, possibly serving strategic or spiritual roles.
