The National Theatre (Národní divadlo) in Prague is a historic Czech theatre that opened in 1881. It is located on the bank of the Vltava River in the Old Town of Prague, and it is considered one of the most important cultural institutions in the country. The theatre showcases both drama and opera performances, and has played a significant role in shaping Czech culture.

The building of the National Theatre was designed by Josef Zítek and Josef Schulz, and it is considered one of the most important works of Czech Neo-Renaissance architecture. The theatre features a grandiose exterior with a façade adorned with sculptures of famous Czech artists and musicians, such as Bedřich Smetana and Antonín Dvořák. The interior of the theatre is also beautifully decorated, with frescoes and other artwork by renowned Czech artists.

The National Theatre has hosted many famous productions throughout its history, including the world premiere of Antonín Dvořák's opera "Rusalka" in 1901. The theatre was also the site of many significant events in Czech history, including the declaration of the independent Czechoslovak Republic in 1918.
