Why is "History of stepwells in Gujarat" trending?

Wikipedia Overview

Stepwells are wells in which the water is reached by steps. They are most commonly found in western India especially Gujarat where over 120 such wells are reported. The origin of the stepwell may be traced to reservoirs of the cities of the Indus Valley civilization such as Dholavira and Mohenjo-daro. Stepwells are a distinctive form of subterranean water resource and storage systems on the Indian subcontinent, and have been constructed since the 3rd millennium BC. The stepwells were constructed in the south western region of Gujarat around 600 AD. From there they spread north to Rajasthan and subsequently to north and west India. Construction activities accelerated during the tenth to 13th century during the Chaulukya and Vaghela periods. The construction of these stepwells hit its peak during the 11th to 16th century. The Muslim rulers of the 13th to 16th century did not disrupt the culture that was practiced in these stepwells and encouraged the building of stepwells. The wells lost their significance in the 19th century due to introduction of water pumps and pipe-systems.
