I went to Saigon Opera House on 18 November 2016.
I went there by walking from Saigon Masjid, and it’s really closeby. The building is well maintained and there’s a construction going on to some part of the building. It’s where every shows performed and there’s a ballet show at the day I visited, unfortunately my time is limited so I couldn’t see the show. From here you can also walk to the park.
These pictures are mine.
