As a result of the War of Vogtland (1354–1357), emperor Charles IV ordered them in 1367 to sell the castle to the Bohemic crown.

In 1422, Sigismund pledged Mylau Castle to the prince-elector of Saxony in gratitude for his services during the Hussite Wars.

One of the members of the rotating burgraves was Joseph Levin von Metzsch (1507–1571), a friend of Martin Luther.

Between 1808 and 1828 it housed the first factory in northern Vogtland of local spinning magnate Christian Gotthelf Brückner (1769–1834).

In the late 19th century, a foundation had the castle rebuilt in historic style to serve as city hall, tavern and museum.

The many modifications in earlier and more recent history makes Mylau Castle a melting pot of styles.
