In Assassin's Creed Unity, which Paris landmark contains the opening playable sequence?

In Assassin's Creed Unity, the opening playable sequence takes place at the Palace of Versailles.

The game begins with a historical prologue in Versailles before shifting to the childhood of Arno Dorian and eventually to revolutionary Paris. Versailles is significant because it was the royal residence and a major center of political power before the French Revolution transformed France. The opening sequence introduces the setting and historical tensions before the main Assassin narrative develops.

Notre-Dame Cathedral and the Louvre are prominent Paris locations later visited in the game, while the Bastille is connected with the revolutionary setting but is not the landmark of the opening playable sequence. Unity is set primarily in Paris during the late eighteenth century and includes cooperative missions for multiple players.
