Despite Colombia's multiple cultural heritage (European, Indian and African), its architecture is mostly the result of adapting European models to local conditions. The country's colonial buildings reflect their Spanish (and particularly Andalusian) origin, as seen in the traditional single-story houses laid around a central patio, to be found both in colonial towns such as Santafé (Bogotá), Tunja or Cartagena, or in rural haciendas throughout the country. After gaining its independence, Colombia severed its links with Spain and looked elsewhere for new models, first England, then France,marking the beginning of what became known as Republican Architecture (Arquitectura republicana), an era that lasted well into the twentieth century, when the changes in architectural thinking in Europe brought Modern Architecture to the country during the last years before World War II.
