The amazing Teatro Regio (Royal Theatre) was commissioned by Vittorio Amedeo II and inaugurated in 1740. It immediately became a reference in the world of opera and ballet, not least for its sophisticated design. Today, the theatre remains a touchstone for the art of opera, but you can also visit the stunning building for its architecture alone. Be sure to check out the intricate bronze Cancellata Odissea Musicale art piece at the entrance.

Located just outside Kuala Lumpur's city centre, this six-tiered Chinese temple honours Mazu, the revered sea goddess. Since its opening in 1989, the active worship site has drawn visitors with its striking architectural features, from the grand prayer hall altars to the tiered roofs adorned with intricate carvings. The temple is open to tourists, but expect devotees filling the temple, burning incense offerings and praying. You can explore independently or join organised tours to appreciate this lesser-known gem's cultural and artistic significance.
