The Vinařice volcano in Central Bohemia has been traditionally interpreted as an erosional remnant of a stratovolcano. However, new observations point to another interpretation. Inclined bedded clast-supported scoriae circumscribe altered scoriae of lower crater facies passing to vent breccia. All these facies represent a relic of a scoria cone. Poorly sorted matrix-supported xenolith-rich pyroclastic deposits form a relic of a tuff ring rounding a maar crater, which was filled with lavas. Therefore, two nested monogenetic volcanoes, scoria cone and maar, fit better to the observed volcaniclastic deposits.
