Trip to National Parliament building is an unforgettable journey through an architectural marvel and Its striking design. The National Parliament Building, or Jatiya Sangsad Bhaban, was designed by the world-renowned American architect Louis Kahn. This is the most notable modern building in Bangladesh and well regarded by many as the finest work of Kahn. Although the typical bold geometrical patterns are distinctive from the outside, a visit to the interior, including the octagonal Assembly Hall, is a special treat.
