In 2004 the music collections of the National Museum, since 1990 scattered over several locations (cf. here), were brought together in the former Maria Magdalena church — very rich collection of instruments, nice presentation - the objects and archivalia in relation to Prague music history not yet displayed — archive of 70.000 recordings (from wax cylinder to cd) — cf. www.nm.cz/ceske-muzeum-hudby.
