Barcelona's El Liceu opened in 1847
and ever since has maintained the status
of one of the world's most important opera houses.
A major portion of the building burnt in 1861 and later in 1994
and needed to be substantially refurbished.
In fact, the Liceu, also known as the Barcelona Opera House,
is the city's top cultural attraction,
as it houses Europe's second biggest hall for operatic performances.
