MONUMENTS SOAK IN SILENCE! With normal life badly affected and the entire country locked down since the Covid-19 outbreak, some of India’s most popular landmarks, that are known for the frenetic energy of lakhs of sightseers who mill around them every day, have been replaced with eerie stillness. The imposing India Gate in New Delhi and the iconic Taj Mahal in Agra are just two of such countless monuments that are together sporting rarely seen deserted looks.
