The history of food at Oxford Castle and Prison is steeped in the site's varied past. Originally constructed in the 11th century, the castle has functioned as a military stronghold, a prison, and a place of execution. Meals for inmates would have been basic and sparse, reflecting the austere conditions of prison life. Common foods might have included bread, gruel, and perhaps the occasional portion of meat for those who could afford it.
In contrast, the castle’s past inhabitants of higher social standing, such as its Norman rulers, would have enjoyed more lavish feasts consisting of various courses with diverse ingredients. However, the food culture of Oxford has evolved massively over the centuries, influenced by the city's academic population and cultural diversity, resulting in a rich culinary scene that encompasses traditional British fare alongside international cuisine.
