The Toad Hill community, located by the Xindian River, is a mountain city built by the military dependents and the dependents of the Taiwan Agricultural Research Institute in the early days, and later by the migrants from the urban and rural areas. The urban development trajectory is preserved in this community, including the water facilities in the Qing Dynasty, the agricultural research layout during the Japanese colonial period, the military landscape of the Sino-American Mutual Defense, the "Huanmin Village" (the only air force dependents village completely preserved in Taipei City), and a self-developed community jointly by military dependents and migrants from the urban and rural areas in Taipei. Due to its diverse historical, cultural, and ecological resources, it was designated as a cultural landscape of Taipei City in 2014. Through the space maintenance and preservation program, we will continue to promote military dependents' village culture, urban agriculture, intergenerational coliving and create an ecological learning area in the Toad Hill.
