The Cathedral-Basilica of Saint Louis, King of France, also called Saint Louis Cathedral, is the seat of the Roman Catholic Archdiocese of New Orleans. Situated in the heart of the city, it is located next to Jackson Square and looks out over the Mississipi River.
The cathedral came into being as a small wooden church in 1718, which would be subject to numerous expansions and reformations over the years.
In 1777, the Assassin Aveline de Grandpré went to the cathedral to be formally inducted into the Templar Order by her stepmother, Madeleine de L'Isle. Unbeknownst to the Templars however, Aveline's induction was a ruse to root out the Templar branch in New Orleans and eliminate its most powerful members. Her ploy a success, Aveline killed Madeleine, who would later be laid to rest within the cathedral's cemetery.
- In the original version for the PS Vita, the cathedral's interior contained an upper level, where Madeleine would originally be defeated. In the HD re-release, the battle with Madeleine is instead held on the ground floor, with the staircase up to the second level remaining inaccessible.
- In reality, the cathedral's recognizable bell tower had not been constructed until 1819.
- One of Jeanne's diary pages could be found at the top of the bell tower.
- It was the tallest building in the city of New Orleans.
