The historic town centre is well preserved and is protected by law as an urban monument zone.

The hilly forested part in the north of the municipal territory belongs to the Křižanov Highlands and includes the highest point of Jemnice, the hill Inženýrský kopec at 602 m (1,975 ft) above sea level.

Jemnice resisted during minor wars, however it was conquered and burned down by army of Matthias Corvinus in 1468.

After that, it was never successfully renewed and the main source of livelihood was agriculture and fish farming.

[3] Jemnice is the terminus and start of a short local railway line from/to Moravské Budějovice.

The last major reconstruction took place in the second half of the 19th century and stables, a brewery and administrative buildings were added.

In the oldest part of the town is the Church of Saint James the Great, which stands on the site of a Romanesque rotunda from the 11th or 12th century.
