Actor Louis Spencer is poised to inherit the childhood home of the late Princess Diana, Althorpe Estate in Northamptonshire, bypassing Princes William and Harry.

The sprawling estate, which covers over 13,000 acres, has been the Spencer family's ancestral home for more than five centuries. This is why the property will pass to their cousin Louis, the son of Earl Spencer, Diana's brother. Despite having three older sisters, 30-year-old Louis, as Viscount Althorp, will inherit the estate due to the aristocracy's system of primogeniture, where titles are passed down to the eldest son rather than the firstborn child.
