After the opera house burnt down in 1823, it was rebuilt in 1823/25. Leo von Klenze, the future court architect of Ludwig I, was in charge of the building work. He made minor changes to the interior, but on the whole kept to Fischer's conception. On the outside, he added the second, smaller portico, which can be seen here. To finance the reconstruction, the so-called "beer penny" was created: an extra tax on the purchase of the Bavarian national drink.
