Earliest evidence of kosher diet in UK found in 800-year-old Oxford animal bones – Latrine of Jewish homes, dated shortly after William the Conqueror’s invitation to Jews to settle in England, features no remnants of pig or other non-kosher animals | Timesofisrael

JTA — Archaeologists in the United Kingdom discovered findings from a medieval Jewish community of Oxford that they said were the earliest evidence of a religious diet.
The findings, locked inside pottery fragments excavated in Oxford, go back to the 12th and 13th centuries following William the Conqueror’s invitation to Jews in Northern France to settle in England.
