| Description: | At the foot of the Železný Mountains, where Heřmanův Městec lies, several mountain forming processes once took place, accompanied by tectonic disruptions, along which the eruption of deep magma occurred, spilling along the surface in the form of lava in certain places. Evidence of the existence of two seas has been preserved in weakly transformed sediments, through which a trail of the same name leads with six stops. |
