The 38 by 31 metre oval clearing of Danilavos piliakalnis

Located in the village of Danilava in the Sužionys eldership, Danilavos piliakalnis is an archaeological site and hill fort. It can be reached by the Sužionys - Danilava road, situated in the northern part of the village, just before reaching the Ilgo ežeras.

The hill fort is situated on a separate hill on the northern shore of Ilgo ežeras. The site features an oval clearing, 38 by 31 metres in size, oriented east-west, with a rise of up to 1.5 metres on the southern side. On the western side of the clearing is a ditch 13 metres wide and 3 metres deep, behind which is a rampart 0.8 metres high atop a 2.5 metre high mound. A second ditch, 0.4 metres deep and 4 metres wide, is excavated further out, followed by what appears to be a second rampart, 1 metre high and 16 metres wide, which now resembles a mound.

On the northern slope, 4 metres below, there is a 3-metre-wide terrace where smooth pottery was found. The northern slope stands 20 metres high, while the southern side is lower. On the eastern slope, 5 metres below the clearing, there is an 8-metre-wide terrace sloping down by 1.5 metres, ending in a 4-metre-wide flat section. A gate is located on the northern slope, and in the northeast foot of the slope, there is an old pit about 2 by 1 metres deep and 0.5 metres deep.

Danilavos piliakalnis is dated to the end of the first millennium BC - beginning of the first millennium BC. The site covers an area of 2.85 hectares and was placed under legal protection by the Non-Real Estate Cultural Heritage Assessment Board on December 13, 2006.
