This new monument in Kolkata is pretty hard to miss, all you need to do is look up. Biswa Bangla Gate, or Kolkata Gate as it is popularly called, is made with two arches that crisscross each other at 55 metres, straddling a road in New Town. A 25-metre-tall, circular tunnel hands on the arches and has been turned into a viewing gallery and a full-fledged restaurant.
