The joint exploration started in June 2016. At that time, a group of Hungarian and Romanian archaeologists opened several small (5 x 5 meter) research sections inside the former church. Their aim was to find the intersection of the main ship and the cross-house, where it was once the place of royal burials. The remaining foundation of the monastery was in a better shape than it was expected. At the foundation of the 2 m thick southern masonry, the researchers managed to observe the formation of one wall. It is an encouraging result that the found wall section were well traceable, not interrupted, ie the former buildings were not demolished in the 19th century. Archaeologists have also found the floor level of the temple. Under the floor more than 50 late medieval tombs and a mongol invasion mass grave which was filled with construction debris and human remains were discovered. However, the exploration of this part faced many difficulties: the proximity of the river Maros was associated with a high level of groundwater, so the research progressed only slowly.
Among other things, a column foundation, a carved piece of medieval door wing; and a red marble sculpture head were found.
In 2017, the full exploration of the mass grave continued. Other interesting artefacts have appeared, such as fragments of a carved mountain crystal object, the closest parallel in the Carpatian Basin is of which is found on the royal scepter of the coronation jewels of Hungary. Among other things, a column foundation, a carved piece of medieval door wing; and a red marble sculpture head were found. These unique artefects testify to the abundance of artistic and cultural wealth of the abbey. During the excavation, new medieval burials were also discovered, which further help to better understand the history of the site.
In addition to the traditional exploration methods, a new kind of documentation technology deployment was provided by the modern technology, the explored surfaces were also documented with 3D photos and the research was supplemented with drone aerial images and geodetic measurements.
In 2017, the full exploration of the mass grave continued.
