A National monument is a monument constructed in order to commemorate something of national importance such as a war or the country's founding. The term may also refer to a specific monument status, such as a national heritage site, which most national monuments are by reason of their cultural importance rather than age. The National monument aims to represent the nation, and serve as a focus for national identity.
A series of structures or areas deemed to be of national importance and therefore afforded protection by the state are part of a country's cultural heritage. These national heritage sites are often called something different per country and are listed by national conservation societies. Romania has listed at least one plant as a national monument, Nymphaea lotus f. thermalis.
