Beyond its grand architecture, Teatro Colon is lauded for its soaring acoustics. In its century-long history, the venue has hosted some of classical music's biggest stars, including Luciano Pavarotti, Maria Callas, Anna Pavlova and Rudolf Nureyev. The auditorium’s central dome was repainted by Argentine artist Raul Soldi in the 1960s, while the whole theatre was later refurbished by the city government and reopened in 2010, as fresh as the day it was inaugurated. Visitors today, as well as watching performances, can join a 50-minute guided tour.
