It was probably founded much earlier as a settlement beneath the castle, but it had the same owner all the time and there was no reason to create records.

[3] The town experienced a rapid development in the 17th century, when the estate was owned by the Vitanovský of Vlčkovice family.

During the rule of Hynek Jetřich Vitanovský of Vlčkovice, Kyšperk greatly improved its state: he had rebuilt the original fortress into a Baroque castle, had built a castle chapel which later became the Church of Saint Wenceslaus, handcraftsmen were allowed to establish guilds, and a hospital for poor and old people was founded.

After World War II, Kyšperk turned into a modern town with a major electrotechnical industry.

[3][4] The OEZ company, manufacturer of circuit breakers, fuses and other wiring equipment, is the largest employer in the town.

[4] The town's football club FK OEZ Letohrad plays in the lower amateur tiers.

Rest of the premises houses a hotel, a school, the cultural centre, and the Museum of Jára Cimrman.
