Task: Question Generation
Input (English): Passage: The Western Chalukya dynastic rule ended in the late 12th century, but its architectural legacy was inherited by the temple builders in
southern Karnataka, a region then under the control of the Hoysala empire. Broadly speaking, Hoysala architecture is derived from a variant of Western Chalukya architecture
that emerged from the Lakshmeshwar workshops. The construction of the Chennakesava Temple at Belur was the first major project commissioned by Hoysala King Vishnuvardhana in 1117 CE. This temple best exemplifies the Chalukyan taste the Hoysala artisans inherited.
Avoiding overdecoration, these artists left uncarved spaces where required, although their elaborate doorjambs are exhibitionistic. Here, on the outer walls, the sculptures are not overdone, yet they are articulate and discreetly aesthetic. The Hoysala builders used soapstone almost universally as building material, a trend that started in the middle of the 11th century with Chalukyan temples. Other common artistic features between the two Kanarese dynasties are the ornate Salabhanjika (pillar bracket figures), the lathe-turned pillars and the makara torana (lintel with mythical beastly figure). The tower over the shrine in a Hoysala temple is a closely moulded form of the Chalukya style tower.When the Vijayanagara Empire was in power in the 15th and 16th centuries, its workshops preferred granite over soapstone as the building material for temples. However, an archaeological discovery within the royal center at Vijayanagara has revealed the use of soapstone for stepped wells. These stepped wells are fashioned entirely of finely finished soapstone arranged symmetrically, with steps and landings descending to the water on four sides. This design shows strong affinities to the temple tanks of the Western Chalukya–Hoysala period.
Output (English): At what location was there an archaelogical discovery of a royal center that showed affinities to the temple tanks of the Western Chalukya–Hoysala?
