This is a local yard display. In France hot air balloons are called montgolfières (in honor of the brothers of the first working balloons in the 1780's).
Today Amboise will have only 8 and 1/2 hours of sun whereas on the Summer Solstice we have about 16 hours of sun. These extremes are because we are above Maine in latitude. Even so, the weather here is milder than in the States year-round, thanks to the Gulf Stream.
What is often called "Bastille Day" in the US, is simply called the 14th of July in France. It's a national holiday and compares to the 4th of July in the US with parades, picnics, music, and of course, fireworks. Alas, this year the latter has been cancelled throughout France due to pandemic restrictions. Paris will have them but watching from nearby (the Eiffel Tower vicinity) will be forbidden so they'll generally be seen on TV. If you want to learn more about this holiday, take a look here. Today's photo was taken last year.
Or maybe it's just the stone path at the base of the levee as seen from its top. Every winter the vegetation dries up and seems to disappear from the levee's sides. And by summer the wildflowers are back in control.
It's quite the contrast to the pre-pandemic market. Now the stands are separated by 25 feet and each has a waiting line marked on the pavement with indicators for proper distancing. So there are fewer vendors and fewer customers. Masks are required for all. But this local icon of commerce and culture is back.
