"Republican Architecture" was the style that prevailed between 1830 and 1930. Although there were attempts to consolidate a modern architectural language, the only examples seen are University City and White City at the National University of Colombia (constructed 1936 to 1939). This work was developed by German architect Leopold Rother, although architects of rationalist trends participated in the design of campus buildings. We also see in Bogotan architecture trends such as art deco, expressionism and organic architecture. This last trend was typified by Bogotan architects in the second half of the twentieth century such as Rogelio Salmona.
