The Nagara and Dravidian architectural styles are two distinct styles of architecture that emerged in ancient India. Both styles have their own unique features and structures that distinguish them from each other. Let's explore these architectural features in detail and compare them.

Nagara Style:

1. Shikara:
- The Nagara style is characterized by a curvilinear tower called the Shikara, which is the most prominent feature of this style.
- The Shikara is usually tall and slender, with multiple tiers or storeys that gradually decrease in size as they ascend.
- The pinnacle of the Shikara is often adorned with an amalaka (a circular stone disk) and a kalasha (a pot-like structure), symbolizing prosperity and spiritual significance.

2. Mandapa:
- The Nagara style incorporates a mandapa, which is a pillared hall or pavilion used for religious ceremonies and gatherings.
- The mandapa is usually square or rectangular in shape and is supported by a series of intricately carved pillars.
- The entrance to the mandapa is often adorned with decorative arches and lintels, showcasing intricate craftsmanship.

3. Garbhagriha:
- The Nagara style places great emphasis on the garbhagriha, which is the sanctum sanctorum or the innermost chamber of a temple.
- The garbhagriha houses the principal deity and is considered the most important part of the temple.
- It is usually square or rectangular in shape and is often adorned with sculptures and intricate carvings.

Dravidian Style:
