In the first decades of the 19th century, Uruguay was in the process of becoming an independent country. In 1830 the first National Constitution was enacted and 6 years later The Plaza Cagancha was built. It was meant to be the central point for the new Montevideo architecture beyond the limits of the Old City walls. Today Plaza Cagancha is considered the “geographical heart” of the country. Being the starting point of the national road system it is also called Kilometer Zero Point.
