List of hillforts in Lithuania

Since 14th century, with the appearance of brick and stone castles, the wooden ones were abandoned and decayed, and today the root "pilis" in "piliakalnis" refers to a castle only etymologically.

In modern times, about one and half thousand places are called piliakalnis, not all of them are real hillforts (defined as elements of terrain with external earth fortifications of closed type with traces of the activity of ancient people within).

A number of similar-looking objects are not hillforts in the archaeological sense, but rather temporary field fortifications, remnants of fortified manors, etc., dated by XVI-XVII centuries.

[2] Detailed information about Lithuanian hillforts is collected at the website Lietuvos Piliakalniai ("Lithuanian Hillforts"),[3] a virtual database maintained by the Cultural Heritage Preservation Force.

The information about the protection status of hillforts and further references can be found in the overall Lithuanian Register of Cultural Heritage [lt].
