Archaeologists excavating the area of the Square of the The Greater Poland uprising (Plac Powstańców Wielkopolskich) in Pleszew, Western Poland, discovered various features and artefacts, including wooden waterworks and coins from the time of Swedish invasion during Second Northern War (1655-60).
The excavations were carried out with connection to the revitalisation of the town square and its surrounding. As part of the revitalisation a reconstruction of local sewage system was needed. This resulted in a discovery of remains of old, wooden waterworks, bridge, and pieces of pottery vessels. Archaeologists speculate that a some sort of a watercourse must have existed here, hence the bridge. In the area of the Poznańska street foundations of an old building and a drain, that once functioned on the surface, were discovered.
Under the square itself archaeologists discovered a well reaching the depth of 3-4 metres, dating to 18-19th century. The well was covered by wooden logs, and was probably for public use as a marked once functioned at the site. Samples of wood have been gathered for dendrochronological analysis.
Among the artefacts are numerous coins, including ones issued by Frederick the Great, King of Prussia (1740-1786) and coins issued between 1659-1668 by John II Casimir, King of Poland and Grand Duke of Lithuania (1648-1668).
