In 2020–2021, within the limits of Trójca – a medieval village located near a ford on the Vistula River that is today part of Zawichost – artefacts were sought with the use of metal detectors. Next, a survey excavation was conducted, resulting in the discovery of e.g. two silver hoards from the 11th and 12th c., single coins from the 11th–12th c. (over 140 specimens) and from later times, merchant’s weights, adornments, minor devotional articles and military accessories (especially from the 11th–13th c.) and many other artefacts. Their discovery makes us suspect that Trójca was one of the most important supralocal trade centres of Lesser Poland in the early Middle Ages. The conducted excavations and research are only the first stage for future archaeological prospections to be conducted in Trójca and will be continued in the years to come.
