The Baghal Citadel of Gurkha History and Frescoes: Rana Sabha Chand to Amar Singh Thapa

Perched dramatically atop a rocky ridge overlooking the terraced green valley of **Arki**, 40 km west of **Shimla** in Solan district, Himachal Pradesh, **Arki Fort (अर्की किला)** is a 17th-century royal palace citadel that bridges Rajput statecraft, Gurkha military conquest, and sublime Pahari miniature art. Founded between **1660 and 1700 CE by Rana Sabha Chand**, the fortress served as the sovereign capital of the **Baghal Princely State**, replacing the earlier seat at Damrila.

Between 1806 and 1815 CE, Arki Fort became the primary operational command and military headquarters of the legendary **Gurkha Commander General Amar Singh Thapa**, who governed the surrounding hill states until his eventual retreat following the Anglo-Nepalese War. In the mid-19th century, **Raja Kishan Singh** transformed the palace interior into an artistic wonderland, commissioning master Pahari artists to paint the walls of the **Diwan-e-Khas** with magnificent frescoes combining Kangra lyrical elegance, Rajasthani miniature styling, and European harbor scenes. The fort preserves grand stone bastions, royal courtyards, and the sacred **Lutru Mahadev Temple**.

"Arki Fort is the hill fortress of dramatic contrasts—where the martial memories of Gurkha General Amar Singh Thapa give way to the delicate, poetic beauty of 19th-century Pahari wall frescoes in the Diwan-e-Khas."
