As the most populous city of Bangladesh, Dhaka has a vibrant cultural life. Annual celebrations for Language Martyrs' Day (21 February), Independence Day (26 March), and Victory Day (16 December) are prominently celebrated across the city. Dhaka's people congregate at the Shaheed Minar and the Jatiyo Smriti Soudho to remember the national heroes of the liberation war. These occasions are observed with public ceremonies and rallies in public grounds. Many schools and colleges organise fairs, festivals and concerts in which citizens from all levels of society participate.
