Final answer:
Paris's churchyard cemeteries, such as the abbey referred to as the 'royal necropolis of France,' are of historical significance due to their roles as burial sites of monarchs and symbols of royal and religious power.
Step-by-step explanation:
Why is Paris at the churchyard cemetery? Assuming that this question is seeking to understand the historical significance of churchyard cemeteries in Paris, it relates to the recognition of Paris as a historic city that has been a center of royal, religious, and civil life for centuries.
The abbey mentioned, often called the "royal necropolis of France,", is historic because it is the burial site of French monarchs and their families, demonstrating the island's evolution as a religious and royal hub from pre-Christian times through the medieval era and beyond.
Key structures like Notre Dame served not only religious purposes but also symbolized the might of the monarchy, enhancing each other's power. Over time, these sites have experienced profound changes, reflected in art and literature, showing shifts in social attitudes towards monuments, death, and religiosity in Paris.
