Inauguration of the Arc de Triomphe in Paris, commissioned by Napoleon after his victory at Austerlitz in 1805.

A major ceremonial celebration marks the construction of the Pont de Pierre, a bridge in Taden, which symbolizes the passage and communication possibilities of the local medieval settlements.
Taden, France | Duchy of Brittany
I could not find any historical record or source that details a ceremonial celebration or the construction of a “Pont de Pierre” in Taden on August 15, 1309. The Pont de Pierre commonly refers to the famous bridge in Bordeaux, constructed much later, from 1819 to 1822. Additionally, detailed historical records from the medieval period, especially concerning specific bridge constructions in smaller settlements, are scarce and often undocumented.
If you have any other date or another historical event in question, I can help provide information on that.
