Modern defense consciousness has shifted from traditional battlefield victories to strategic planning, step by step. Therefore, the public art theme is ‘Between Square and Circle, Planning Before Action,’ presenting a new perspective on modern defense. The public art uses square and circle as the main elements, transforming the use of space to create a new humanistic and artistic atmosphere for the Ministry of National Defense, softening the rigid lines of military institutions. The lively, colorful, and humanistic spirit presented by the artwork echoes the spirit of the new era of defense. The work not only serves as street furniture but also integrates with existing facilities on the base, beautifying the environment and incorporating aesthetic education into daily life.
