He attended Cheam School and later Gordonstoun in Scotland, followed by studies at Trinity College, Cambridge, where he earned a degree in archaeology and anthropology.
Childhood and formative influences

At Cambridge, Charles pursued an interdisciplinary focus that reflected his interests in history, conservation, and architecture. He also studied Welsh at the University College of Wales, Aberystwyth, a commitment to language that signaled his intent to engage deeply with the nations of the United Kingdom. These experiences shaped his emphasis on sustainability, architecture, and community-led initiatives that would later define parts of his philanthropic and royal work.
