Bahía Blanca's Municipal Theatre is one of the most impressive civic buildings in the city — a handsome Italian-influenced structure from the early 20th century that reflects the prosperity the city enjoyed during the wheat and wool export boom. The interior is particularly fine, with a traditional horseshoe-shaped auditorium, ornate plasterwork, and good acoustics.
The theatre hosts a regular season of opera, classical music, and drama from March to December. Ticket prices are modest by European standards, and the quality of local productions is often surprisingly high. If you are in Bahía Blanca over a weekend, checking what is on at the Teatro Municipal is well worth the effort.
