The Nagara style of temple architecture, predominantly found in Northern India, is characterized by its distinctive curvilinear shikhara (tower) that rises from a square base. Unlike the Dravidian style, it typically lacks elaborate boundary walls or gateways (gopurams). The temple plan usually includes a garbhagriha (sanctum sanctorum) where the main deity is housed, an antarala (vestibule), and one or more mandapas (halls) for devotees. The shikhara is the most prominent feature, often appearing as a series of miniature architectural elements (urushringas) that gradually diminish in size as they ascend, culminating in an amalaka (a stone disc with a ribbed surface) and a kalasha (pot-like finial) at the very top. There are variations within the Nagara style, such as the Rekha-Nagara (simple curvilinear shikhara), Phamsana (shorter, broader shikhara with a straight slope), and Valabhi (rectangular building with a vaulted roof). Sculptural decoration is integral, adorning the exterior walls with deities, mythical creatures, narrative panels, and mithunas (erotic couples), often arranged in horizontal bands. The entrance is frequently guarded by dwarapalas (door guardians) and sometimes features river goddesses like Ganga and Yamuna. The temples are typically built on a high plinth (jagati), and while a pradakshina patha (circumambulatory path) might exist, it is often integrated within the main structure rather than being an external feature. Materials commonly used include sandstone, granite, and brick, depending on the region.
