【法國。波爾多。皮埃爾橋 Pont de Pierre】

橫跨加龍河上的美麗古典橋梁

First bridge over the Garonne River at Bordeaux, it was planned and designed during the First French Empire, under the orders of Napoleon I, but its construction took place during the Bourbon Restoration, from 1819 to 1822.[1] During these three years, the builders were faced with many challenges because of the strong current at that point in the river. They used a diving bell borrowed from the British to stabilize the bridge's pillars. It has seventeen arches (number of letters in the name Napoléon Bonaparte). On the sides, each pile of bricks is capped by a white medallion in honor of the emperor. It also carries the coat of arms of the city (three intertwined crescents). It was the only bridge until the construction of pont Saint-Jean in 1965
