a+u’s March issue features the architecture, landscape, and cities of Colombia. A land of intoxicating natural beauty, Colombia has employed architecture as a key agent in rebuilding its cities and civil society as it recovers from decades of civil strife stemming from drug trafficking and guerrilla warfare. Photographic work by Camilo Echavarría illustrates how travels through the country cause one to feel a homogeneous, abstract passage of time. With no seasons, architecture is conditioned by various landscapes formed by the rich geographic diversity across regions. Medellín-based architect and guest editor Camilo Restrepo Ochoa takes us on a journey through his country, where architects create spaces as ＂types, elements, and instruments of architecture made to question limits, to build an inhabitable threshold that participates in the spatial experience of moving from outside to inside.＂ Works by 14 architectural practices across 3 generations are presented in this issue. Also featured is the city of Medellín’s remarkable achievement of reinvigorating its poorest neighborhoods through mobility and urban space. Text in English and Japanese.
