The article presents a brief summary of newly discovered wooden structures in the well-known polycultural site Mohelnice – štěrkovna (also “U cukrovaru” or Za cukrovarem) in the Mohelnice cadastre and its vicinity. Earlier discoveries at this site include Neolithic timbered wells and a sensational find of an oak monoxylon from the La Tène period of the 4th/3rd century BC (dendro 281 or 301 BC). It was found trapped in its home port on the banks of the meandering river Morava and dating has revealed the same age as the absolutely dated simple wooden pole construction. It is the northernmost found monoxylon known in the Czech Republic and also presents the oldest evidence for such use of ships on Czech rivers. The manufacture and use of such ships has been known since the Mesolithic period continuing until modern times. The subsequent exploration of the shores of the Moravičany Lakes banks revealed a number of smaller wooden structures below the water surface, either made up of pointed stakes themselves, or a combination of smaller stakes and branches built into a tapered corridor resembling a structure used for fishing. The latest discovery is a massive oak-fir structure manufactured from stakes, longitudinal and transverse planks and stones, interpretable as a timber trackway, or a bridge. It has been dendrochronologically dated to 1547–1560 and archival sources indicate the structure was repaired in 1645. The structure spans the former meander between Třeština and Mohelnice near one of the mills. The existence of this route is documented on 18th-century maps. Significant discoveries from various times of mainly wooden buildings underscore at least the European significance of the Mohelnice site. It may yield many valuable finds in the future.
