One Family Has Held Some of London's Richest Land Since 1677 — How Did They Keep It?
In 1677, a twelve-year-old heiress named Mary Davies married into the Grosvenor family, bringing with her 500 acres of undeveloped marshland on the western edge of London. That land would become Mayfair and Belgravia — today the most expensive real estate in Britain. Nearly 350 years later, the Grosvenor family still owns the ground beneath these streets, and the current Duke of Westminster, just 35 years old, controls a fortune worth over £9.5 billion.
This is the story of how one family turned a patch of London swamp into a permanent empire — using strategic marriages, the leasehold system, private Acts of Parliament, and a trust structure so effective that when the sixth Duke died in 2016, his son inherited billions while paying almost no inheritance tax. From Hugh Audley, the notorious 17th-century moneylender who first bought the Manor of Ebury, to Thomas Cubitt, the master builder who transformed the Five Fields into Belgravia's white stucco terraces, to the modern Grosvenor Group operating in 62 cities worldwide — this is the full story of how land, law, and patience built one of the most enduring fortunes in history.

I think the main issue is that leasehold should be abolished
I stayed on Ebury St a few years ago at The Lynton Hotel was a lovely stay , the owners were two brothers and because I was an Australian guest they put Vegemite on the breakfast buffet- I will always cherish that memory
