The 700-year-old St. Vitus Cathedral in Prague inaugurates a new organ

Prague’s 700-year-old St. Vitus Cathedral inaugurated a new organ, blessed at mass and played by the Czech Philharmonic (including Dvořák), with eight concerts planned to showcase it.
Built by renowned maker Gerhard Grenzing in Spain, the instrument has four keyboards and about 6,000 pipes ranging from 7 mm to over 7 m; it was shipped in pieces and reassembled in Prague.
The project took roughly 14 years and was largely crowd-funded — a 2017 campaign raised more than 135 million CZK (about $6.5M) — to replace an undersized, unreliable 1930s organ.
