1. Why Blenheim?

In 1700 Louis XIV’s huge ambitions and his large, powerful army had ensured France had not lost in battle for 50 years. But in 1704 John Churchill, Earl of Marlborough put a stop to this. Against all odds his army conquered the French outside a town in Bavaria called Blenheim. Queen Anne wanted to honour the Earl and commissioned prestigious architects John Vanbrugh and Nicholas Hawksmoor to design a magnificent baroque palace in the grounds of a royal hunting park, as a monument to the Battle of Blenheim. The Palace replaced the Royal Palace of Woodstock, a Tudor palace 200 metres away on the other side of the river.

2. Equal rights at Blenheim

The first Duke of Marlborough had no surviving sons which led parliament to introduce legislation enabling the estate to be passed to a female heir or through the female line. Thus the second holder of Blenheim Palace was in fact a woman. A younger daughter, Lady Anne Churchill, married Charles Spencer, 3rd Earl of Sunderland (c. 1674-1722), and from this marriage descended the modern Dukes of Marlborough. Originally they bore the surname Spencer but George Spencer, the 5th Duke of Marlborough, obtained a Royal Licence to assume and bear the additional surname and arms of his famous ancestor, the 1st Duke of Marlborough, and thus became George Spencer-Churchill.

The Dukedom of Marlborough is the only Dukedom in the United Kingdom that can still pass in the female line. The succession for the Dukedom is as follows:

1. The heirs-male of the 1st Duke’s body lawfully begotten;

2. His oldest daughter and the heirs-male of her body lawfully begotten;

3. His second and other daughters, in seniority, and the heirs-male of their bodies lawfully begotten;

4. His oldest daughter’s oldest daughter and the heirs male of her body lawfully begotten;

5. All other daughters of his daughters and the heirs male of their bodies;

6. And other descendants into the future in like fashion, with the intent that the Marlborough title never become extinct.

3. Blenheim Folklore

Before the Palace was built Henry II used to keep his mistress Rosamund Clifford in a cottage in the grounds of Blenheim Palace. Legend has it that a labyrinth led to the cottage, ensuring only the King himself could reach it – until his wife, the formidable Eleanor of Aquitaine grew suspicious.

A thread from a tapestry Rosamund Clifford was weaving caught on the King’s spur as he left the cottage, leaving a clear trail for his wife, direct to the front door. Rosamund was offered death by the sword or by poison but while she was being taken to London she escaped and took refuge in a convent nunnery at Godstow near Oxford in 1176.

The stones from this convent were used to build many of the buildings in the area, including the Trout Inn, featured in the Inspector Morse television series.

4. Blenheim is a World Heritage Site

In 1987 the United Nations selected Blenheim Palace to join the Great Wall of China and the Pyramids as a World Heritage Site. As a monument to the Battle of Blenheim, an exquisite example of English Baroque and of Capability Brown’s landscaping, the Palace was considered by selectors to have been of prime importance to human development. The Palace is the only historic house in Britain to be bestowed with this honour.

5. Blenheim’s marriage of Convenience

Blenheim Palace was in a dire financial situation when the 9th Duke of Marlborough inherited the title in the 1890s. Money was urgently needed so the Duke set off for America in search of a rich bride. Seventeen-year-old Consuelo Vanderbilt fitted the bill perfectly. Her father was the Bill Gates of Victorian America, and in marrying her, Blenheim Palace became £3/4 billion richer. After 10 years the marriage came to an end – both parties happily remarried and Blenheim Palace remained financially buoyant.
