National Martyrs’ Memorial is the national monument of Bangladesh. The architecture is composed of seven pairs of triangular-shaped walls or prisms; the outermost pair being the shortest in height but widest in span, the inner pairs gradually change their aspect ratio and the innermost pair thus forms the peak point of the architecture. Each of these seven pairs of walls represents a significant chapter in the history of Bangladesh.
