The last on my list, but no less interesting Kolkata also known as Calcutta. There are many historic buildings in the city. The most significant of these is the William Fortress, dating back to the seventeenth century. It was built by British colonists. When visiting Kolkata, it is worth visiting the Great City Park, the old university, the Raja Palace, which are few in this city, and the temples dedicated to goddess Kali. This is a city that travelers either hate or love.
