Landscape architecture serves as an integral tool in shaping the built environment, where design not only meets aesthetic and ecological goals but also plays a pivotal role in promoting cultural and historical awareness. Through careful manipulation of space, materials, and symbolism, landscape architects create public and private environments that communicate the collective memory, identity, and heritage of communities. This paper analyses how landscape architecture fosters an understanding of cultural history, memorializes important events, and highlights indigenous practices through the design of public spaces, gardens, memorials, and urban landscapes. By examining case studies from around the world, this paper demonstrates how landscape architecture can educate, commemorate, and inspire reflection on historical and cultural contexts.
