National symbols of Bangladesh

It consists of a red disc on top of a green field, offset slightly toward the hoist so that it appears centred when the flag is flying.

The red disc represents the sun rising over Bengal, and also the blood of those who died for the independence of Bangladesh.

The four stars represent the four founding principles in the current constitution of Bangladesh of 1972: nationalism, secularism, socialism, and democracy.

The outer white ring is shown with the caption of the official name of the Government of the People's Republic of Bangladesh in Bengali: গণপ্রজাতন্ত্রী বাংলাদেশ সরকার with 4 red 5-pointed stars.

Amar Sonar Bangla (আমার সোনার বাংলা, "My dear Bengal") is a song written and composed by the Bengali poet Rabindranath Tagore, the first ten lines of which were adopted in 1972 as the national anthem of Bangladesh.

These songs were meant to rekindle the unified spirit of Bengal, to raise public consciousness against the communal political divide.

Every 21 February, people from all parts of the Bangladesh head to the Shaheed Minar in the probhat feri, a barefoot march to the monument, to pay homage to those killed in the language movement demonstrations by singing this song.

The enormous design includes half-circular columns to symbolize the mother, with her fallen sons, standing on the monument's central dais, and the red sun shining behind.

There is an artificial lake, a reflecting pool, a pair of twin bridges, a picturesque garden and several mass graves in front of the main monument.

Throughout the Bangladesh Liberation War in 1971, a large number of teachers, doctors, engineers, poets and writers were systematically massacred by the Pakistan Army and their local collaborators, most notably the alleged militia groups Al-Badr and Al-Shams.

The initial proposal for a memorial at Rayer Bazaar was brought forward by Projonmo '71 (an organisation of children of martyrs of the Liberation War), which also laid a temporary foundation stone in 1991.

The main attraction of the monument is a 50-meter high tower, composed of stacked glass panels, that stands at the place where the Pakistani Instrument of Surrender was signed at the end of the Liberation War.
