Worse disasters came in the 17th century, when the town was hit by Swedish incursions during the Thirty Years' War and the plague epidemic.

After the Seven Years' War, during the rule of Prince-Bishop Philipp Gotthard of Schaffgotsch, a new prosperous period for the town began.

[3] After Schaffgotsch's death in 1795, Javorník partially lost its importance, but remained economic centre with developed crafts and textile manufactories.

Javorník was recovering only slowly and never regained the same importance in the region as it had during the golden age in the second half of the 18th century.

The Czechoslovak soldiers were disarmed and abducted to Germany where they were interned by local authorities in the concentration camp in Paczków.

Many of them were also beaten and killed by numerous militias and paramilitary groups with strong ties to the Communist Party and the Red Army.

[3] Following the Communist coup d'état of 1948, Czechoslovak government confiscated most of the property which belonged to the Roman Catholic Archdiocese of Wrocław, their forests were divided among state-owned enterprises.

[3] By the mid-1960s, the only major employers in Javorník were a small manufacturer of metal furniture and a company producing stuffed toys.

As the social conditions in the town continued to deteriorate, in the 1980s the Communist government decided to build here a subsidiary of MEZ Postřelmov (electrical engineering plants).

[10] The castle complex of Jánský Vrch is the main landmark of the town, protected as a national cultural monument.

Other valuable buildings in the town centre are burgher houses from the 19th century with medieval cores, mostly in Mannerist and Empire styles.
