Unseen Treasures of The Portland Collection Opens 25 March 2023

Unseen Treasures of The Portland Collection, at the Harley Foundation, North Nottinghamshire, offers a new, revealing look at this world-class art collection. 

The Portland Collection, built up over 400 years by a single aristocratic family, is vast and varied. Exhibitions in its dedicated museum change every three years. 

For this display, opening 25th March 2023, visitors will enter a museum filled to the brim with fascinating art and objects, a giant cabinet of curiosities. There will be silver and tapestry, paintings and jewels; art that has come home after a long loan to a prestigious national gallery, and stunning star items that visitors know and love – such as Michelangelo’s ‘Madonna of Silence’ or the pearl earring worn by Charles I at his execution. 

A highlight of the display is a Picture Gallery, stacked with Tudor and Jacobean portraits – many of which have never been seen publicly before.

Lisa Gee, Director of The Harley Foundation, explains: 

“It is said that a picture paints a thousand words, so what do these portraits tell us? Historic portraits were almost always flattering, filtered images which are like the social media of their day. But behind the gleaming fabrics and jewels were fully rounded individuals. Despite their starched clothing they were as human as we are.” 

Highlights from Unseen Treasures of The Portland Collection include: 

Lady Margaret Stuart, Countess of Nottingham, by Paul van Somer, c.1620. 

A rarely shown portrait which shows the Countess wearing an elaborate dress with an improbably plunging neckline. This was in the style of Queen Anne – it revealed her power and status, as well as her decolletage. 

– Map cabinet, inlaid with ebony and ivory, c. 1625. 

Thought to be one of just six made, and the only one in the UK. This intricately inlaid cabinet shows an early map of the world, taken from Ortelius’ 1570 Theatrum Orbis Terrarum, widely considered to be the first modern atlas. 

Silver wine fountains, by Adam Loofs, c. 1688. 

These monumental display pieces were commissioned for William of Orange, later King of England, and gifted to Hans Willem Bentinck, who was to become the 1st Earl of Portland. Old silver such as this is rare – most large pieces were melted down to make new, more fashionable showstoppers. This is believed to be the only surviving pair and one of the highlights of the spectacular silver in The Portland Collection. 

The Horsemanship Tapestries, by Wauters after Diepenbeke, 1660. 

William Cavendish, ancestor to the Dukes of Portland, was one of the great horsemen of his day. He literally wrote the book on horsemanship, which led to the modern art of dressage (a copy of ‘The Horsemanship Book’ is also on display). These tapestries were woven from the Abraham van Diepenbeke illustrations in his book, and we believe that only eight sets, each of five designs, were made. You can see three of these huge textiles in the display (the others can be seen at Welbeck Abbey, on tours of the State Rooms which will run during March and April).

– Bess of Hardwick, in the style of Rowland Lockey, c. 1587. 

The Countess of Shrewsbury, aka Bess of Hardwick, was the mother of the Cavendish dynasty, ancestor of the Portland family, and an icon of Tudor England. This is believed to be the primary copy of her most famous portrait.

The Harley Foundation has invited different experts to explore Unseen Treasures and create gallery trails. Pick up a leaflet and have Dr Karen Hearn (Tate, UCL) or Hannah Obee (Wallace Collection, Chatsworth, Harewood House) take you on a journey. You might learn about celebrity in Tutor Britain, the surprising story of a conjurer turned calligrapher who made a self-portrait with microscopic text, or how embroidery could save your life – and earn you an Earldom.

Unseen Treasures of The Portland Collection, opens at the Harley Foundation, North Nottinghamshire, on 25th March 2023. It will be open 6 days a week and is free to enter. 

Unseen Treasures of The Portland Collection will open at The Harley Foundation on 25th March, 2023. It will be on show for 3 years.
