Why is "Art Deco in Kolkata" trending?

Wikipedia Overview

The Art Deco in Kolkata, India is a prominent architectural style which can be found across the city, most notably in the southern parts of the metropolis. The style can be traced back to the 1930s "with the use of Portland cement and with geometrical articulation in plan and cosmetic decorative treatment including perforated concrete grill-work on a simple elevation (façade)." Although Kolkata is notable for its colonial-style and vernacular-style buildings, the emphasis on Art Deco buildings while discussing the architectural history of the city is often overlooked. This is in exception to the few prominent art deco buildings constructed during the colonial period in the first half of the twentieth century—about which enough has been written. Despite art deco being so prominent in the latter half of the twentieth century insofar as entire neighbourhoods—architecturally speaking—appeared to be adaptations of one style, it was not paid enough attention up until the twenty-first century when many such buildings started to be either severely neglected or demolished because of lack of architectural and historical awareness and preservation efforts.
