Here is the Arc de triomphe de l'Étoile in Paris. Its construction took 30 years, ending in 1836. Its initial purpose was to celebrate the Napoleon's victory at Austerlitz, but now it honours the fallen French soldiers of Revolutionary and Napoleonic wars, as well as World War I.
This scale in probably not the best for this size of structure, but now it fits well with the Eiffel Tower, also in 1/3 scale. I hope I still managed to get its key features. It was built in 1.17.1 so works with that and higher versions. As usual, I used Greenfield Texture Pack for 1.17 and Chocapic 13 V8 Ultra shader for the pictures. Enjoy)
