Well, I'll not be able to give the entire conclusion but definitely, I will be able to provide some guidelines.
First, write about how the Mughals came to India. Write about the main Mughal kings who built architectural marvels. Then write about how these marvels beautify our country and also give it economic benefit in terms of revenue. Then you can add something about maintaining the beauty of these structures by not spoiling the wars and throwing litter.
I hope this answer helped you.:)
