Gorgeous opera building from late 19th century. Newly reconstructed as of 2020. Part of the National theatre institution (incl. Estates theatre, National Theatre, New scene on the NT and the State opera) so you can buy the tickets on their webpage (you dont have to print them out, sufficient to just have them on your smartphone). Dresscode unfortunately not enforced, but PLEASE,don't be the odd moron who will walk in a historical opera building in a T-shirt or sneakers. Opera pieces have in general Czech and English subtitles both above the stage and on the screens attached to each seat. Changing rooms are for free of course, refreshment bars available and toilets are clean and functional. If you are above 185 cm, you might have issues folding your legs as the space at some places challenges that of the lowcost airlines.
