A seventeenth-century religious treasure stolen from a church in southern Poland nearly 30 years ago has been formally handed back to Polish authorities in Paris, after French police discovered the missing artefact at a commercial stall and identified it using Interpol’s database of stolen cultural property.
The elaborate, gilded monstrance was stolen during the night of 14–15 July 1997 from a parish church in Moskorzew, a village in Poland’s Świętokrzyskie region.
Its disappearance remained unresolved for almost three decades until French investigators located the object earlier this year.

On Monday, 12 October 2026, representatives of the French police formally transferred the recovered artefact to Polish officials during a ceremony at the Polish Embassy in Paris.
According to reporting by the Polish Press Agency, the object is expected to be transported to Poland shortly.
Its physical arrival in the country has not yet been confirmed.
A religious treasure stolen in a single night
The recovered object is a monstrance, an ornamental vessel used in Catholic worship to display the consecrated Eucharistic host.
Often made from precious metals and decorated with elaborate craftsmanship, monstrances have played an important role in European religious art for centuries.
The Moskorzew example dates from the seventeenth century and features openwork decoration and gilded elements.
Tomasz Śliwiński, a cultural-property restitution official at Poland’s Ministry of Culture and National Heritage, provided details of the object’s history during the Paris ceremony.
He confirmed that the monstrance had been stolen overnight between 14 and 15 July 1997.
According to Śliwiński, it was the only object taken during the burglary, suggesting the thieves had deliberately targeted it.
Historical records also establish that the monstrance was already present in Moskorzew during the first half of the nineteenth century.
The object’s earlier history, including its original maker and the circumstances in which it arrived at the parish, has not been established in the available reporting.
French police recognised the object using Interpol
The breakthrough came in spring 2026, when French authorities informed the Polish Embassy that they had located the missing monstrance.
Officers from France’s National Directorate of Judicial Police, based in Nanterre near Paris, had encountered the artefact at a commercial stall.
Investigators were able to recognise it using information recorded in Interpol’s PSYCHÉ database, which contains details of stolen and missing cultural property.
The case involved France’s specialist Office central de lutte contre le trafic des biens culturels (OCBC), the national police unit responsible for combating trafficking in cultural objects.
The French Ministry of Culture explains that its national stolen-art records are linked to Interpol’s international database, allowing investigators to compare objects discovered on the market with documented thefts.
Philippe Guichard, a French police official involved in the handover, emphasised the importance of the database in identifying cultural objects that may have disappeared many decades earlier.

Interpol’s Stolen Works of Art database contains descriptions and photographs of approximately 57,000 missing and stolen items from around the world.
It includes information supplied through authorised police and international heritage organisations.
The system also supports searches using photographs, helping investigators compare objects with recorded losses.
In the Moskorzew case, that international record helped French officers identify a religious artefact that had been missing since the 1990s.
Authorities have not publicly established, in the reporting available, how the monstrance reached France, who possessed it during the intervening decades or whether any prosecution will follow.
A formal handover at the Polish Embassy
Monday’s ceremony marked the formal transfer of the recovered monstrance from the French authorities to Polish representatives.
Wiesław Tarka, Poland’s chargé d’affaires in Paris, thanked the French investigators and emphasised the importance of recovering cultural objects stolen from Poland.
He said the country’s efforts to retrieve lost and illegally exported artworks were continuing, with its Culture Ministry working alongside Polish diplomatic missions abroad.
Tarka credited the French police, particularly the OCBC, with the careful investigation that made the monstrance’s identification and recovery possible.
French representatives also stressed the significance of returning an object that holds religious as well as historical importance.
Śliwiński thanked the French investigators for their cooperation, including OCBC representative Nathalie Chanvallon.
The ceremony represented the formal handover, rather than the completion of the object’s journey.
Polish officials said arrangements would be made for the monstrance to return to the country, but did not provide a confirmed arrival date.
Its eventual destination, including whether it will be returned directly to the Moskorzew parish, has not yet been publicly established.
Poland’s wider effort to recover stolen heritage
The monstrance’s recovery forms part of Poland’s continuing effort to retrieve cultural property removed through theft, war and illegal export.
The programme encompasses religious objects, historic manuscripts, paintings, archival material and other artefacts held in public and private collections abroad.
In an April 2026 overview of its restitution work, Poland’s Culture Ministry said 101 objects had returned to the country in 2025 through 25 restitution cases.
The ministry described a process involving archival research, checks of auction catalogues and online sales listings, museum documentation and international cooperation with police and customs authorities.
The Moskorzew recovery illustrates a different but complementary approach: using an international police database to identify a stolen object decades after its disappearance.
It was also the second ceremony of its kind in France involving Polish cultural property in 2026, according to the PAP account reproduced by RMF24.
In February, Polish authorities recovered a fifteenth-century manuscript stolen from a library in Wrocław.
The two cases demonstrate the role French investigators have played in tracing and recovering cultural objects taken from Poland.
The final stage of a 29-year journey
For the parish in Moskorzew, the monstrance’s recovery brings an important development in a case dating back to the summer of 1997.
Its survival and identification also demonstrate the value of maintaining reliable records of stolen cultural property.
The object was missing for almost 29 years before being located in France, and its discovery was made possible by investigators recognising it through a cross-border information system.
With the formal handover completed in Paris, the next step is the monstrance’s physical transfer to Poland.
No confirmed date for that journey has yet been announced.
