Thrissur is also known as the cultural capital of Kerala because of its cultural, spiritual and religious leanings throughout history.[6] The city centre contains the Kerala Sangeetha Nadaka Academy, Kerala Lalithakala Akademi and Kerala Sahitya Academy.[7] The city hosts the Thrissur Pooram festival, the most colourful and spectacular temple festival in Kerala.[8][9] The festival is held at the Thekkinkadu Maidan of Vadakumnathan Temple in April or May, in the Malayalam month 'medam'.[6]
