Der Veitskopf is the cinder cone of a volcano that erupted during the Quaternary period. Because there are no reference strata, its age cannot be accurately estimated. The Veitskopf produced three lava flows, of which the first and easily the largest spread out northwards from the crater rim in the west. Because the neighbouring valley, the Gleeser Tal, was formed after the eruption of the Veitskopf, this lava flow stands above the present valley and forms the so-called Mauerley. The two lava streams that run in a southerly direction are nowhere near as large and were first identified from magnetic surveys because they were covered by a layer of pumice. At the top of the Veitskopf is the Lydia Tower which enables an all-round view that includes the Laacher See, the Brohltal valley and even the Siebengebirge hills.
