The Saigon Opera House in Ho Chi Minh is an elegant colonial building at the intersection of Le Loi and Dong Khoi Street in District 1, very close to the famous Notre Dame Cathedral and the classic Central Post Office. The restored three-storey 800-seat Opera House was built in 1897 and is used for staging not only opera but also a wide range of performing arts including ballet, musical concerts, Vietnamese traditional dance and plays. Performances are advertised around the building and information can be found in the state-operated tourist information centre close by.
The exterior has the appearance of polished pearl and makes a great place to photograph – especially at night when bathed in a soft, orange light. The entrance is through a vaulted archway that is kept in immaculate condition; inside, expect swathes of red velvet, classical friezes and hardwood floors. Although the official name of the building is The Municipal Theatre of Ho Chi Minh it is by far more commonly known as the Saigon Opera House and after the restoration work in 1995, the building is just as it was at the turn of the 19th Century.
