Early History
Treasurer’s House sits close to what was the outer wall of the Roman fortress of Eboracum. Excavations under the basement have revealed the edge of the major Roman road that ran roughly along the line of today’s Chapter House Street.
Centuries later, the whole area was enclosed as a private precinct around York Minster, with the site of today’s Treasurer's House being where the Treasurer of the Minster had his great mansion. During the Middle Ages the Treasurer oversaw the money and treasures of the Minster and was second only to the Minster Dean. Their large house reflected this important status.
The Youngs
The office of Treasurer was abolished in 1547, part of the Reformation of the Church under Henry VIII. By then, their mansion was already “much in decay” and was purchased by the Archbishop of York, Robin Holgate (c.1481-1556), probably as a private investment.
By the 1560s it was owned by Archbishop Thomas Young (1507-1568). It passed to his wife, Jane (1530-1614) and their young son, George (1567-1620) after Thomas died. Little is known about George Young other than he was knighted in 1604 and had earlier served in the English army in Ireland around 1599. He became the owner of the house in 1588 at the time of his marriage. It subsequently passed to his son and grandson.
During this period, the old medieval mansion seems to have been completely rebuilt in at least two phases and was grand enough to host King James I when he stopped in York en route to Scotland in 1617.
Thomas Fairfax
In 1648 the Young family sold the house to William Belt (c.1580-1652), Town Clerk for York. Belt died soon after and his family sold it on. The new owner was one of the most important political figures in Yorkshire, Sir Thomas Fairfax (1612-1671). Fairfax had risen to national prominence as commander of the Parliamentary army during the English Civil War, but by the time he bought the house, he had effectively retired from politics. Fairfax had other property in and around York and it is unclear whether this new purchase was used or further modified by him, or was simply an investment. During the War the Fairfax family had prevented the more extreme religious elements of the Parliamentary army from damaging the Medieval beauty of the Minster windows and interiors. Perhaps Fairfax buying the house directly behind the great east window was a way of keeping a protecting presence through the 1650s?
The Aislabies
In 1663, following the restoration of the monarchy, Fairfax sold up to a new ‘up and coming’ man, George Aislabie (1618-75). Aislabie had made a lot of money as a senior legal official for the Church and through an inheritance and was keen to buy the prestigious city property. The same year Thomas married the daughter and eventual heir of Sir John Mallorie of Studley Royal (now NT). It was involvement with the Mallory family that would lead to his death; in 1675 George died on the steps of his house having been mortally wounded a few streets away in a duel fought over his sister-in-law’s honour
The property passed to George’s three sons in turn, eventually being inherited by the youngest, John Aislabie (1672-1742), who would sell the house in 1698. Aislabie was M.P. for Ripon and the income from the sale may have helped support his re-election that year.
