The history of Wentworth Castle Gardens

Connections to slavery

Although recognised as one of the UK's greatest 18th century landscaped estates, the house and gardens Thomas Wentworth had built are closely tied to the Transatlantic Slave Trade.

In 1713, he was instrumental in securing for Britain the lucrative monopoly to transport and sell enslaved people from African countries to the Spanish empire. The design of his grand house and garden was in part a celebration of his pride in this ‘achievement'.

Thomas also made direct profit from the trade, partly from shares he owned and partly through his marriage to Anne Johnson (c.1684–1754) whose family were deeply involved in the slave trade by building ships for the East India Company and working for the Royal African Company. 

The sundial

In 1711, Wentworth was appointed joint negotiator of the Treaty of Utrecht, which ended the long War of the Spanish Succession. As part of these negotiations, Britain gained the monopoly to supply enslaved people from African countries to the Spanish colonies in the Americas – known as the ‘Asiento.’

Wentworth considered the treaty a crowning achievement in his diplomatic career and something to be proudly represented in his house and gardens. This included a sundial, now in the conservatory, in the form of a kneeling African man – a legacy of the enslavement of Africans and the objectification of Black bodies in British and European art. 

Lady Mary Memorial

‘To the memory / of the Rt. Hon. / Lady Mary Wortley Montagu / who in the Year 1720 / Introduced Inoculation / of the Small Pox into / England from Turkey’.  

An example of an extremely early memorial dedication to a non-royal woman was probably added to an older monument by Thomas’ son, William (1722–91). It's also known as the Sun Memorial.

Lady Mary Wortley-Montagu (1689-1762) was a poet and letter-writer, well known for her travel writing, including descriptions of Muslim women and their lives in the 18th century Ottoman Empire. Her life and work continues to fascinate and she is seen by many today as a proto-feminist and historic LGBT+ figure.

Tackling smallpox

After seeing inoculation against smallpox practised in Constantinople (now Istanbul), she made British medical history by helping to make it fashionable in British high society during the 1720s. William Wentworth and his three sisters were all treated to protect them from the terrible disease. 

It is not certain when the monument, which is a copy of an ancient obelisk in Rome, was first erected. It originally had a bronze disc on top which was rumoured to be angled to reflect the sunlight across to the Wentworth Woodhouse estate. Could this be another example of family rivalry on show? It has also been suggested that the name is also an 18th century pun on ‘sun’ and ‘son.’  

Argyll Column 

In 1744, William Wentworth dedicated this grand column to his late father in law, the 2nd Duke of Argyll. Shortly before his death, the Duke had been punished for opposing the government's harsh anti-Jacobite policies in Scotland. This column dedicated to his memory is topped with a statue of Minerva, the Roman goddess of wisdom and war, who faces south to London. Was William making a subtle political comment with this monument?
