Coțofenești helmet stolen in 2025 nears end of restoration, to go on display in January 2027

Theft and recovery

The Coțofenești helmet, a Dacian princely helmet, and three Dacian bracelets were stolen on 25 January 2025 from the Drents Museum in Assen, the Netherlands, just before an exhibition on the Dacians closed. G4Media reported that the thieves used explosives to force their way into the museum, then broke open the display cases and took the objects. The helmet and two of the bracelets were recovered in early April 2026, more than a year after the theft. They reached Romania on 21 April 2026 under a special forces escort. Restoration work is now carried out in the laboratory of the National History Museum of Romania (MNIR).

Restoration work

On Monday, 2 November 2026, the MNIR presented the helmet in the presence of Culture Minister Ioana Ciocan and Deputy Prime Minister Marian Neacșu. The restoration was led by Alexandru Dozsa, a museum specialist whose surname some outlets spell Doja. Dozsa said the most serious problem, the flattening of the helmet, was solved with methods that had not been tried before.

“Methods are experimental, I tell you this because we have not worked in this way before.”

Dozsa explained that the deformations were corrected by pressing the object between two moulds of thermoplastic material placed inside and outside it, which pushed the metal past its plastic zone. He said the helmet was shaped piece by piece, guided by a replica in the museum's collection, because its pre-theft form is documented only in photographs. Cornel Ilie, the MNIR's general director, said the helmet is now very close to its original shape.

What remains

The MNIR said the helmet cannot yet be displayed in its normal position, because the right cheek guard (obrăzar) came loose at the site of an earlier museum intervention from 2019 and the object lacks the stability needed for display. Ilie described the next step in these words.

“The last stage of the restoration will consist of reattaching that cheek guard, which had been restored before and came loose, but this process raises far fewer problems.”

The museum's specialists said the helmet is for now displayed horizontally on a conservation cushion, so that no pressure falls on areas that may be fragile. A second and more complex stage will restore the helmet to its original diameter, since it still shows slight flattening. Știrile PRO TV, citing people involved in the project, reported that a few retouches remain, including reattaching a side piece.

Exhibition and investigations

At the presentation, Culture Minister Ioana Ciocan announced the plan for the helmet to return to public view.

“I spoke a little earlier with Mr Cornel Ilie and, for National Culture Day, a special exhibition will be built, which will also contain the helmet.”

Before the restoration, investigations were carried out with the Horia Hulubei National Institute for Physics and Nuclear Engineering (IFIN-HH) and with experts from the Dutch National Heritage Agency. The analyses used non-invasive methods, including optical and digital microscopy, X-ray fluorescence and scanning electron microscopy. They found that the detachments caused by the theft occurred in areas restored earlier, especially at joins applied during a 2021 intervention. No new deep cracks affecting the structural integrity of the artefact were identified, and the analyses confirmed the object is made of natural electrum, an alloy mainly of gold and silver. According to Ciocan, about ten Romanian and Dutch specialists were involved in the evaluation and restoration stages. Mihaela Simion, the museum's deputy director, said the theft is part of the object's history and that returning it to its absolutely original form is not a standard of good practice.
