The name "Colombo", first introduced by the Portuguese in 1505, is believed to be derived from the classical Sinhalese name Kolon thota, meaning "port on the river Kelani". It has also been suggested that the name may be derived from the Sinhalese name Kola-amba-thota which means "Harbor with leafy mango trees". However, it is also possible that the Portuguese named the city after Christopher Columbus.
