The Hotel Nacional Rio is a skyscraper hotel in the São Conrado neighbourhood of Rio de Janeiro, Brazil. The 108-metre, 34-storey building was constructed from 1968 until 1972 and designed by famed architect Oscar Niemeyer, who was considered to be one of the key figures in the development of modern architecture. The hotel closed in 1995 following a steady decline in customers and the proximity to a crime ridden neighborhood. It was restored and reopened in 2017.
