Udayagiri & Khandagiri Caves — Emperor Kharavela's Rock-Cut Monasteries

Hewn into the twin sandstone hills of Udayagiri and Khandagiri on the western outskirts of Bhubaneswar, these extraordinary 2nd-century BCE rock-cut caves stand as eastern India's earliest architectural monuments—commissioned by the mighty Kalinga Emperor Kharavela as contemplative monasteries (*lenas*) for Jain monks.

The Twin Hills of Kalinga's Golden Age

Rising abruptly from the coastal plains on the western edge of Bhubaneswar in Khordha district, the twin sandstone ridges of Udayagiri ('Sunrise Hill', 137 feet high) and Khandagiri ('Broken Hill', 123 feet high) preserve peninsular India's most important collection of non-Buddhist rock-cut architecture. Hewn primarily during the 1st and 2nd centuries BCE under the patronage of the illustrious Mahameghavahana (Chedi) dynasty, these caves—totaling 18 on Udayagiri and 15 on Khandagiri—were excavated not as elaborate royal palaces, but as austere residential retreats (*lena*) and meditation chambers for wandering Jain Digambara ascetics (*arhats*).

Following the devastation of the Kalinga War waged by the Mauryan Emperor Ashoka in 261 BCE, Kalinga regained its sovereign might and commercial glory under its greatest native ruler, Emperor Kharavela (c. 1st century BCE). Kharavela championed Jainism while upholding an enlightened policy of religious tolerance. To commemorate his military conquests and provide enduring shelter for ascetics during the four months of the monsoon retreat (*chaturmasya*), he commissioned master stonecutters to sculpt the living rock of the Kumari hills into multi-level monasteries adorned with lively relief carvings depicting royal processions, court dances, animal allegories, and everyday civilian life in ancient Kalinga.

The Hathigumpha Inscription: An Invaluable Historical Chronicle

The crown jewel of Indian epigraphy is housed in Cave 14 of Udayagiri, known as Hathigumpha (the Elephant Cave). Here, carved upon the vaulted overhanging brow of a natural cavern, lies a monumental 17-line inscription executed in the ancient Brahmi script and Prakrit language. Discovered by A. Stirling in 1820 and definitively deciphered by James Prinsep, Bhagwanlal Indraji, and K.P. Jayaswal, the Hathigumpha Inscription is one of the most comprehensive biographical records of any ancient monarch in world history.

The inscription chronologically documents the first thirteen regnal years of Emperor Kharavela with meticulous precision:

• Youth & Education (Lines 1–3): Describes Kharavela's early training in correspondence, currency, accounting, civil law, and military arts until his coronation as King of Kalinga at age 24.
• Military Triumphs (Lines 4–12): Records his campaigns against the Satavahanas in the Deccan, his routing of the Rathikas and Bhojakas in the west, his capture of Gorathagiri (Barabar hills), and his siege of Rajagriha in Magadha, forcing King Bahasatimita (Brihaspatimitra) to bow at his feet.
• Recovery of the Kalinga Jina (Line 12): Triumphantly recounts how Kharavela recovered the sacred idol of the *Kalinga Jina* (the revered Jain icon of Rishabhanatha), which had been carried away as war booty by the Nanda rulers of Magadha three centuries earlier.
• Civic Works & Canal Excavation (Lines 5, 13–17): Details his extensive reconstruction of Kalinga's hurricane-battered capital (*Kalinganagari*), the extension of the ancient Tiwasari irrigation canal excavated by the Nandas 300 years prior, and the construction of the cave monasteries on the Kumari hills for Jain ascetics.

Masterpieces of Rock Architecture: Rani Gumpha & Ganesh Gumpha

Architecturally, Rani Gumpha (Cave 1, the Queen's Cave) on Udayagiri is the largest and most magnificent rock-cut monument at the site. This double-storeyed monastery surrounds an open central courtyard on three sides, featuring intricately carved pillared porticos, guardian sentries (*dvarapalas*), and sculpted narrative friezes that represent the zenith of early Indian decorative art. The upper gallery reliefs depict dramatic scenes of a royal hunt, the abduction of a maiden, a king and queen enjoying an acrobatic dance performance accompanied by an orchestra of harpists and drummers, and playful monkeys scampering across mango trees.

Nearby lies Ganesh Gumpha (Cave 10), named for a later relief of Lord Ganesha carved into the interior cell wall during the Bhauma-Kara period. Guarded at its entrance by two freestanding carved stone elephants clutching lotus blossoms in their trunks, the cave features upper friezes illustrating the famous romantic folk tale of King Udayana of Vatsa and Princess Vasavadatta of Ujjain, highlighting the rich secular storytelling tradition shared across ancient India.

Sculptural Motifs & Monastic Living Quarters

A closer architectural examination of the cell chambers reveals how ingeniously ancient master craftsmen adapted sandstone rock to the austere requirements of Jain Digambara monastic life. The cave ceilings are deliberately low, preventing standing worship and obliging ascetics to sit or recline in meditative contemplation. The stone floors are tilted gently toward the front entrance to prevent rain accumulation, while the rear portions feature sloping ledges carved directly from bedrock to serve as stone pillows (*ushnisha*). Small horizontal niches carved into the rear walls provided oil lamp sconces and storage alcoves for water pots and monastic whisks (*rajoharana*).

Artistically, the pillar bracket capitals exhibit extraordinary sculptural virtuosity. Carvers adorned the brackets with winged horses, mythical lions (*vyalas*), caparisoned elephants carrying lotus buds, and celestial Gandharvas bearing garlands. The tympanums over the cell doorways are framed by ornate semicircular arches (*toranas*) springing from the mouths of makaras, filled with motifs of sacred trees, pairs of pigeons, and running deer—motifs that directly influenced the later classic Kalinga temple architecture of Bhubaneswar's 7th-to-11th-century shrines.

Khandagiri: Medieval Jain Tirthankara Shrines

While Udayagiri is predominantly an early Chedi-era complex, the adjacent hill of Khandagiri underwent significant religious artistic rejuvenation centuries later under the Somavamsi dynasty (10th–11th centuries CE). Jainism continued to flourish here alongside the Shaivism of Bhubaneswar, as evidenced by caves adorned with exquisite medieval sculptures of the 24 Jain Tirthankaras:
