Palacio Rio Negro
Avenida Koeler 255
Dating back to circa 1889, the Palacio Rio Negro is a captivating edifice built by the Baron of Rio Negro for a retreat during the summers. However, after the Proclamation of the Republic, the palace and the adjoining buildings were given away to the state as a summer residence for the state's governor. In 1903, the Palacio Rio Negro became a possession of the Federal Government after which it has been serving as a summer retreat for the successive Presidents of the country. The awe-inspiring facade of the Palacio Rio Negro is the only thing accessible to visitors since an internal visit is prohibited.
