Ubi Papa Ibi Roma

Durham Castle and Cathedral, along with similar sites like Auckland Castle, hold unique significance not merely due to formal architectural similarities but as prime objects or parts of a sequence. This study challenges the conventional approach of comparing palaces solely based on stylistic resemblances, such as those seen in 14th-century Spanish, Italian, and French structures. Instead, it posits that a palace's importance lies in its role as an innovator or its position within a developmental lineage. If a building is a 'prime object,' it represents the first instance of an architectural innovation, regardless of its origin. Conversely, if it is part of a sequence, it reflects the influence of a preceding model. This approach reframes how we assess the historical and cultural impact of palaces like Durham Castle, emphasizing their role in architectural evolution rather than mere stylistic comparison.
