Kolkata is known for its literary, artistic and revolutionary heritage; as the former capital of India, it was the birthplace of modern Indian literary and artistic thought.[222] Kolkata has been called the "City of Furious, Creative Energy"[223] as well as the "cultural [or literary] capital of India".[224][225] The presence of paras, which are neighbourhoods that possess a strong sense of community, is characteristic of the city.[226] Typically, each para has its own community club and on occasion, a playing field.[226] Residents engage in addas, or leisurely chats, that often take the form of freestyle intellectual conversation.[227][228] The city has a tradition of political graffiti depicting everything from outrageous slander to witty banter and limericks, caricatures and propaganda.[229][230]
