Hradiště Kolo, Hillfort in Týnec nad Labem, Czech Republic.

Hradiště Kolo is a hillfort in Týnec nad Labem that preserves the remains of a fortified ancient settlement. The site is defined by raised earthen ramparts and ditches that form the original defensive system.

The hilltop was first fortified in the Hallstatt period and again in the La Tène period, when an oppidum stood here. Surface finds collected by František Dvořák in the early 20th century dated the site to the La Tène culture; Jan Filip initiated a long-term survey carried out by Jiří Hrala from 1951, and Zbyněk Sedláček led larger excavations in the 1970s. A 2014 rescue dig in the outer bailey found 68 Celtic coins and fragments, 55 of them silver obols, one struck from a die also known at Stradonice.

The site shows traces of an ancient settlement that people inhabited and modified over centuries. Visitors can still see remains of defensive walls that reveal how residents protected their community.

The fortification sits on Kolo hill at 225 m, on the northernmost spur of the Železné hory, at the eastern edge of Týnec nad Labem; the entrance in antiquity was on the western side. The ramparts survive as a stone band about 130 cm wide and a 1.3–2 m strip of stones behind a post hole. The terrain is unmarked woodland; sturdy shoes help.

Its location near the Elbe River allowed inhabitants to monitor trade routes and control goods passing through. This position made the settlement an important trading hub in ancient times.
