History of Cragside

Begun in 1863 as a small sporting lodge, the estate expanded over three decades. Its pleasure gardens were developed into a grand fantasy landscape that were both beautiful and functional.

It became a place of pioneering experimentation – the first place in the world to be lit with hydroelectricity and a showpiece of engineering prowess. Explore how the Armstrongs created a Victorian vision of the future.

Meet the Armstrongs

William George Armstrong (1810–1900) was an engineer and industrialist who changed the world with his inventions. His works on the banks of the Tyne manufactured hydraulic machinery, armaments and battle ships, exporting them across the globe. It was from this international trade that Armstrong made the vast wealth that funded Cragside.

In 1835, Armstrong married Margaret Ramshaw (1807–1893). Margaret was instrumental to the development of Cragside, bringing extensive botanical knowledge to the creation of the gardens. She was also great friends with the groundbreaking Victorian naturalists, John and Albany Hancock. Her endowments helped to establish institutes such as the Great North Museum and Newcastle University.

Britain’s original smart home

Illuminated by hydroelectricity and powered by hydraulics, Cragside was a place like no other. Central heating, electric light, gravity-fed plumbing, water-powered machinery and a hydraulic lift provided an unrivalled level of comfort.

Among Cragside’s many innovations was the wonder of electric light. In 1878 carbon-arc lamps were installed into the Gallery, casting a spectacular if glaring light. Armstrong collaborated with the chemist Joseph Swan, and in 1880 the Library saw the first domestic installation of his recently invented incandescent lightbulbs. The cloisonné vases that were adapted as lamps still sit on the bookcases.

Designing the house

For much of their time at Cragside, the Armstrongs lived on a building site. The original 1863 house was extended in three phases between 1870 and 1884 by architect Richard Normal Shaw.

Cragside was not Shaw’s first project with the Armstrongs. He had already completed extensions to the freestanding banqueting hall at Jesmond Dene, the Armstrongs’ Newcastle villa until 1884. The young Scottish architect would become known for his signature ‘Old English’ style – an inventive mixing of historical styles of architecture. Built in stone quarried from the estate, the mansion appears to rise from the rocks. With astonishing skill, Shaw designed a house at Cragside that looked both entirely modern and as if it had existed forever.

The first phases of expansion in 1869 saw marvels such as the installation of a plunge bath and central heating system, and the addition of dramatic turrets and towers. Inside, the interiors still showcase Shaw’s lavish combinations of ebonised furniture, gothic carving and Pre-Raphaelite stained glass.

In 1872, the Armstrongs approved Shaw’s plan for a vast extension, creating a new entrance hall, staircase and gallery. There was a new tower called Gilnockie, in tribute to a tower with the same name connected to the legendary Armstrong family of border raiders. At the top of Gilnockie Tower was an observatory (later replaced by bedrooms) from where Armstrong could stargaze.

Shaw also created the Owl Suite of guest chambers, named for the decorative finials on the walnut beds. The bedrooms contained plumbed-in washstands and a bathtub. There was even a private toilet. In 1884, this suite was used to host the Prince and Princess of Wales, as was the magnificent new Drawing Room with its six-metre-high marble fireplace.

The final rooms built at Cragside were designed not by Shaw but by architect and antiquarian Fredrick Waller. The 1895 Billiard Room is Jacobean revival style, with classical columns, fitted furniture and carved panelling. A further, smaller space became Armstrong’s experimental laboratory where he spent his later years capturing photographs of electrical discharges.

A grand fantasy garden

Driven by their shared love of natural sciences, the Armstrongs oversaw the planting of millions of trees and shrubs at Cragside. Following a fashion for North American planting styles, they created a Pinetum of non-native conifers on the banks of their fantasy valley garden. Inspired by the Himalayas, they planted a unique collection of rhododendrons. Their collective ambition saw the transformation of a bare moorside into a man-made paradise.

The couple had already experimented with dramatic artificial landscapes at Jesmond Dene. Their ambitious approach met the challenges of an estate dominated by difficult terrain and fulfilled Amstrong’s desire to harness water. An enormous Rock Garden was formed around the House, engineered waterfalls enlivened the natural burn and five vast lakes were created.

In the Formal Gardens, elaborate carpet beds and herbaceous borders showed off the skills of Head Gardener, Henry Hudson. Specially adapted glass houses allowed the growing of palms, ferns and succulents from the southern hemisphere. The Orchard House – now the only surviving building from the complex – enabled fruits to be grown out of season in wild Northumberland.

An engineer’s playground

William Armstrong adapted emerging technology to harness waterpower. His innovations made Cragside famous, but Armstrong’s private project relied on the technology of other inventors, as well as the work of an army of estate workers.

One of Armstrong’s first creations was Tumbleton Lake. Water from this lake powered a machine which pumped spring water up to another reservoir above the House. In turn, this was gravity fed down to the House, providing plumbed water and powering the hydraulic lift. Even the roasting spit in the kitchen was turned by a miniature water mill.

Armstrong’s early experiments with electric lighting were small scale, but in time he built a second hydro-electric power station to cope with increasing demand. Water from the additional artificial lakes at Nelly’s Moss supplied the turbine-operated dynamos, still present at Burnfoot Power House.

Cragside and the global armaments market

Armstrong began his engineering career with hydraulic machinery, but his vast wealth was later founded on the sale of armaments. Armstrong invented a revolutionary style of field gun. It was breech-loaded, meaning that shells could be fed into the back of its barrel rather than muzzle. This made it safer to use, more accurate and longer ranging.

In 1859 Armstrong was awarded a knighthood when he gifted his gun patents to the British government.

Armstrong’s efficient new armaments were particularly attractive to countries who sought to modernise their militaries. Visitors to Cragside and the Elswick Works included high-profile dignitaries from countries like China, Thailand (formerly Siam), and Japan.

Dignitaries from Japan included two future prime ministers. The weaponisation of the Japanese Navy by Armstrong companies is considered a deciding factor in the Japanese defeat of China in the Sino-Japanese War. Today Cragside’s collections reflect these cultural and political exchanges. Of note are gifts likely given to the family by members of the Japanese elite, including a significant collection of Japanese woodblock prints and ceramics.

The Armstrongs as collectors

The Armstrongs decorated the House with contemporary art, fashionable furniture and scientific collections. Their 3,000 shells are still displayed in the Gallery in specially designed cases, as are taxidermy pieces by John Hancock.

The Armstrongs collected work by contemporary British artists, including Millais, Leighton, Holman-Hunt, Rossetti and Turner. Most of these paintings were sold in 1910, to pay the debts of Cragside’s inheritor, William Watson Armstrong. A few remain on display, along with family portraits and work by local artist, Henry Emmerson.

20th–century and the Watson-Armstrongs

William and Margret did not have children and so their great-nephew, William Watson Armstrong (1863–1941), inherited. Two further generations of Watson-Armstrongs lived at Cragside, although Bamburgh Castle became the family’s main residence.

Cragside and the National Trust

In 1977, Cragside was transferred to the National Trust. The House subsequently underwent an extensive restoration project. This included the uncovering and reproduction of historic wallpapers and paint finishes, and the purchase and borrowing of items to create settings in showrooms. Work is still ongoing to unpick the details of the restoration.

Cragside opened to the public in 1979 and the formal gardens were acquired in 1991. Acquisitions and bequests have revitalised the collections, including technological objects related to the formal gardens as well as non-associated works such as J.M.W. Turner’s ‘Kilgarren Castle’ from 1798-9.

Today, Cragside is still a place of engineered beauty that sparks curiosity. Current projects include a re-presentation of Margaret Armstrong’s sitting room at the House as a flexible exhibition space, and the conservation of the Orchard House at the Formal Gardens.
