This 19th-century neo-Renaissance monument has some of the cleanest, brightest stonework in the city. Designed by Josef Zítek and Josef Schulz and completed in 1884—it was named for then Hapsburg Crown Prince Rudolf—the low-slung sandstone building was meant to be a combination concert hall and exhibition gallery. After 1918 it was converted into the parliament of the newly independent Czechoslovakia until German invaders reinstated the concert hall in 1939. Now the Czech Philharmonic has its home base here. The 1,200-seat Dvořákova síň (Dvořák Hall) has superb acoustics (the box office faces 17 Listopadu Street). To see the hall, you must attend a concert.
