It's difficult to give an exact number of forts in India as there are numerous forts spread across the country, and new ones are still being discovered and identified.
India has a rich history of fortification, and many forts were built by various rulers and empires over the centuries for defensive purposes or as centers of governance. Some of the well-known forts in India include the Red Fort in Delhi, the Amer Fort in Jaipur, the Chittorgarh Fort in Rajasthan, the Gwalior Fort in Madhya Pradesh, and the Golconda Fort in Hyderabad.
According to the Archaeological Survey of India (ASI), there are more than 3,600 protected monuments in India, which includes forts, palaces, temples, and other historical structures. It's important to note that not all forts in India are protected, and many are in a state of ruin or have been lost to time.
