Jemčina Castle, Medieval château in Jemčina, Czech Republic.

Jemčina is an 18th-century hunting lodge built for Prokop Vojtěch Černín on the site of a horse stud founded in 1673, with Anselmo Lurago as architect. Side wings added in 1766–1770 enclose a cour d'honneur, and a 19-metre chapel of St John of Nepomuk with frescoes by Jan Quirin Jahn and stucco by Carlo Bossi stands on the building.

A horse stud founded in 1673 by Count Jan Jáchym Slavata preceded the lodge; Prokop Vojtěch Černín had a hunting lodge built on the site in the mid-18th century, with Anselmo Lurago as architect. It was modified in 1757–1760, side wings added in 1766–1770, and in 1790 Jan Rudolf Černín adapted it for battues and parforce hunts. The state took over after the 1923 land reform, the army held it from 1950 to 1991, and it has been closed to the public since 2019.

The name Jemčina is linked to the Černín family, who built the hunting lodge here in the mid-18th century. The chapel of St John of Nepomuk, 19 metres high, holds frescoes by Jan Quirin Jahn and stucco work by Carlo Bossi, and was reconsecrated in May 2004.

The château is closed to the public, so visits are limited to its exterior. A road between Hatín and Novosedly nad Nežárkou passes the grounds, and a red hiking trail from Šimanov to Velká Holná runs by. Three marked trails start here: yellow to Evženovo Údolí, green to Drahov, blue to Novosedly nad Nežárkou.

The 19-metre Chapel of St John of Nepomuk, added in 1766–1770, holds the castle's most valued feature: fresco decoration by painter Jan Quirin Jahn of Prague and stucco work by Carlo Bossi. The organ was assembled by Josef Horák of Dačice.
