National symbols of Bangladesh

The national Flag of Bangladesh (বাংলাদেশের জাতীয় পতাকা), known as Red-Green, was adopted officially on 17 January 1972. 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 green field stands for the lushness of the land of Bangladesh.^[1] The flag is based on a similar flag used during the Bangladesh Liberation War of 1971, which had a yellow map of the country inside the red disc. In 1972 this map was deleted from the flag. One reason given was the difficulty for rendering the map correctly on both sides of the flag. The civil ensign and naval ensign place the national flag in the canton of a red or white field, respectively.

The seal features the same design elements as the first Flag of Bangladesh in a circular setting. 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. In centre the country map on a red disc.

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. The Central Shaheed Minar of Dhaka goes up to a height of 14 metres (46 ft) and was made with marble stones. The stairs and barrier are highlighted in white, to create a divine look. The fence on both sides is painted with lines from poems of legendary poets in iron letters. As the visitors enter the monument they will find two statues of the patriots who sacrificed their lives in that heinous police firing of 1952. The marble floor was designed to reveal the moving shadows of the columns. The basement of the Shaheed Minar also included a 1,500-square-foot (140 m²) mural representing the history of the Language Movement.^[24]

The Language Movement was one of the formidable movements which has come up in the country of Bangladesh, thus the Central Shaheed Minar epitomizes efforts to represent the spirit of Bangladeshi nationalism and also highlight the importance of the Bengali language in the social and cultural progress of the country. As a result, the Shaheed Minar has a very significant place in the social and cultural mechanism of Bangladesh. At present, all national, mourning, cultural and other activities held each year, regarding 21 February, have been centered around the Shaheed Minar.

The monument is composed of 7 isosceles triangular pyramid shaped structures, with the middle one being the tallest. The highest point of the monument is 150 feet. There is an artificial lake, and several mass graves in front of the main monument. There is a Green house, PWD site office, VVIP and VIP waiting room inside the area.

During the entire duration of Bangladesh Liberation War of 1971, a large number of teachers, doctors, engineers, poets and writers were systematically massacred by Pakistan Army and their local collaborators, most notably the alleged Islamist militia groups Al-Badr and Al-Shams. The largest number of assassinations took place on 14 December 1971, only two days before the surrender of Pakistan army to the joint force of Indian army and Mukti bahini. The initial proposal for a memorial at Rayer Bazar was brought forward by Projonmo 71 (organisation of the children of the martyrs of liberation war), who also laid a temporary foundation stone in 1991.
