Zámecká Křižíkova elektrárna, vodní mlýn a elektrárna v Jindřichově Hradci

Zámecká Křižíkova elektrárna is a hydroelectric power station and former watermill in Jindřichův Hradec, standing between the castle and the castle brewery on the Hamerský stream. Its pale facade has a triangular pediment, a stone plaque with coats of arms and the inscription "V roce 1933" and "Křižíkova elektrárna", and an arched wooden double door. Inside are two Francis turbines with a combined output of 75 kW and a head of 4.95 m.

The mill is first mentioned in the 15th century, when the miller Ondřej bought it for 18 Prague kopa. Jáchym z Hradce enlarged and rebuilt it in 1551, as recorded on a stone relief bearing his coat of arms and that of his wife Anna of Rožmberk. It burned in 1615 and again in 1773, was rebuilt in 1853 to a plan by engineer Gustav Hannak, and at the end of the 19th century Count Eugen Czernin had it converted into a water power station equipped by František Křižík.

The mill's name U Čtrnácti ("At the Fourteen") recalls the 14 water wheels it had after its 1673 rebuilding. Since the late 19th century the site has housed a power station equipped by František Křižík, and today a museum inside presents the history of the power station, fishpond farming and forestry.

The mill stands between the castle and the castle brewery on the Hamerský stream, just before it joins the Nežárka. The museum inside covers the history of the power station, fishpond farming and forestry. The building is a listed cultural monument and part of the castle's national heritage site.

The mill burned down during the Jesuit seminary fire of 1615 and was restored only in 1673, when it ran on 14 water wheels. It burned again in the castle fire of 1773. Its first known miller, Ondřej, bought it for 18 Prague kop and sold it four years later for 36 Meissen kop.
