By the late 1800's the palace had fallen into disrepair and the 9th Duke of Marlborough had no funds to refurbish it.
Prevented by the strict social dictates of late 19th-century society from earning money, he was left with one solution; he had to marry money. In November 1896 he coldly and openly without love married the American railroad heiress Consuelo Vanderbilt. The marriage was celebrated following lengthy negotiations with her divorced parents: her mother was desperate to see her daughter a duchess, and the bride's father, William Vanderbilt, paid for the privilege. The final price was $2,500,000 (worth about $62m in 2007) in 50,000 shares of the capital stock of the Beech Creek Railway Company with a minimum 4% dividend guaranteed by the New York Central Railroad Company. The couple were given a further annual income each of $100,000 for life. The bride later claimed she had been locked in her room until she agreed to the marriage. The contract was actually signed in the vestry of St. Thomas Episcopal Church, New York, immediately after the wedding vows had been made. In the carriage leaving the church, Marlborough told Consuelo he loved another woman, and would never return to America, as he "despised anything that was not British".
The replenishing of Blenheim began on the honeymoon itself, with the replacement of the Marlborough gems. Tapestries, paintings and furniture were bought in Europe to fill the depleted palace. On their return the Duke began an exhaustive restoration and redecoration of the palace. The state rooms to the west of the saloon were redecorated with gilt boiseries in imitation of Versailles. Vanbrugh's subtle rivalry to Louis XIV's great palace was now completely undermined, as the interiors became mere pastiches of those of the greater palace. While this redecoration may not have been without fault (and the Duke later regretted it), other improvements were better received. Another problem caused by the redecoration was that the state and principal bedrooms were now moved upstairs, thus rendering the state rooms an enfilade of rather similar and meaningless drawing rooms. On the west terrace the French landscape architect Achille Duchêne was employed to create a water garden. On a second terrace below this were placed two great fountains in the style of Bernini, scaled models of those in the Piazza Navona which had been presented to the 1st Duke.[citation needed
