The foundation stone for the memorial, which is set to be built on the triangular Place du Petit Marché alongside Niamey city hall in the capital of Niger, was laid earlier this week.
"The martyrs' memorial is a commemoration to all those lost in the fight against terrorism along Niger's southern and western borders," said the studio.
"It is conceived as a monument to those who lost their lives, a tangible documentation of the continuous fight against extremist entities and the soldiers who have fallen in the process."
The memorial will consist of a grid of 56 concrete, four-pointed-star-shaped columns that rise 20 metres into the air from a raised plaza within the triangular site.
The plaza will be flanked on either side by trees that will also be planted in a gridded formation.
"As visitors approach the memorial, they are engrossed in a labyrinth of abstraction through a rhythmic interplay of light, shadow and geometries amplified by the form of the 20-meter-high pillars," explained the studio.
"Each pillar symbolizes the individuals lost, extending towards the Niamey sky whilst grounded and situated in its urban context," continued the studio.
"At night, beams of light projecting from the pillars become part of the urban skyline, acting as both a beacon of remembrance and a visual guide toward the civic heart of Niamey."
Below the raised plaza a large room will be created to be used for civic events.
Described by the studio as an "underground cooling labyrinth", the space will be broken by the concrete columns that pass through it to their foundations.
These columns are designed to act as thermal chimneys to reduce heat build up around the memorial.
Adjaye Associates was established by David Adjaye in 2000. The British-Ghanaian architect was recently awarded the RIBA Royal Gold Medal. To celebrate we rounded up ten of the studios most significant projects.
The studio previously created a simple memorial pavilion for South African trumpeter Bra Hugh, is working with Ron Arad to design a UK Holocaust memorial and designed a Mass Extinction Memorial Observatory for the Isle of Portland in England.
