About the Bhitargaon temple:

• It was built in about the 5th-6th century CE, during the later Gupta period.
• It is considered the oldest surviving brick temple in India with a tall pyramidal or curvilinear tower (shikhara), and one of the earliest Hindu shrines with a roof and a high tower.
• It is built entirely of bricks and decorated with large terracotta panels showing Hindu deities (such as Vishnu and Shiva), mythological scenes, animals and ornamental designs.
• It stands on a square plinth, with a sanctum (garbhagriha) entered through a porch.
• It faces east.
• It was damaged by lightning in the 19th century; the upper part of the tower and the porch were partly destroyed.
• It was surveyed by Alexander Cunningham in the 1870s.
• It is protected by the Archaeological Survey of India as a monument of national importance.

Gupta temple architecture:

The Gupta period (about 320-550 CE) is called the "Golden Age" of ancient India, and it saw the beginning of structural Hindu temples (earlier shrines were mostly rock-cut).

Early Gupta temples were small, with a flat roof, a square sanctum and a pillared porch. Example: Temple 17 at Sanchi (Madhya Pradesh), one of the earliest structural temples.

Later Gupta temples began to have a shikhara (tower) over the sanctum, which later developed into the north Indian temple style.

Other important Gupta temples:

• A stone Vishnu temple at Deogarh (Lalitpur, Uttar Pradesh), one of the earliest with a tower.
• Parvati Temple, Nachna Kuthara (Panna, Madhya Pradesh).
• Bhumara Shiva Temple (Satna, Madhya Pradesh).
• Tigawa Temple (Katni, Madhya Pradesh).

Other Gupta-period art:

• The Udayagiri caves (near Vidisha, Madhya Pradesh), with the large Varaha (boar) sculpture.
• The Ajanta paintings (some of them).
• The Iron Pillar at Mehrauli, Delhi, which has not rusted for about 1,600 years.
