Sir John Spencer
1455 - 1522
Sir John was the founder of Althorp. He grazed sheep here from the 1480s and in 1508, impressed by the quality of the land, he bought the land, and built the house. Sir John already owned an estate and mansion in Wormleighton in Warwickshire: the house there was four times the size of Althorp. By putting down roots at Althorp, Sir John provided what was to become a home for the next 19 generations.
