Řivnáč, Archaeological hillfort in Czech Republic.

Řivnáč is a prehistoric fortified settlement located on a hilltop in Czech Republic. The site contains the remains of defensive walls and structures that still define the landscape today.

Řivnáč was settled in the Eneolithic by people of the Řivnáč culture, which takes its name from this hill. In the 19th century it became the first explored Eneolithic hilltop settlement in Bohemia; Čeněk Ryzner led excavations in 1881–1883 and Ivan Borkovský examined the faint remains of the rampart in 1948. Finds include Řivnáč, spherical amphora, funnel beaker and bell beaker pottery, plus early medieval occupation and a hoard of over a hundred deniers from around 1012.

The site shows how early communities built and defended their settlements on hilltops. The remains and artifacts found here reveal aspects of daily life and organization from that distant period.

Marked hiking trails lead to the site, with informational panels along the way explaining what you encounter. The best time to visit is during dry weather when you can see the surrounding landscape clearly from the hilltop.

In the settlement pits at Řivnáč, archaeologists found daub with impressions of posts and wickerwork, the first such find in Czechia. This led to the idea that prehistoric dwellings had sunken floors and clay-plastered walls. The site also yielded over a hundred deniers from around 1012, evidence of early medieval activity.
