Was watching Emily in Paris, and saw an India Gate lookalike in Paris

Yes because India gate is inspired by Arc ade Trimphe

And you can climb on the top of it. If I try to do the same here, I would get beaten up.

A similar lookalike is present in Mumbai as well.

Yea. Tbh though ours is their look alike.
They constructed it like more than 100 years earlier I think
