LT2015 m. buvo atliekami žvalgomieji tyrimai ir žvalgymai Bobriškio sentikių cerkvės (UK 30760) teritorijoje (Rokiškio r., Kriaunų sen.), ant Sartų ežero kranto esančiame Bobriškio kaime. Bobriškio sentikių cerkvė yra kaimo R dalyje, 110 m į P nuo Sartų ežero kranto. Žvalgomųjų tyrimų metu suprojektuotos elektros kabelio trasos vietoje ištirti trys 2x1 m dydžio šurfai (bendras plotas-6 m²). Jie išdėstyti tarp pagrindinio įėjimo į cerkvę, šalia jos V fasado ir šventiko namo, stovinčio prie šventoriaus P pakraščio, kuris sutampa su saugomos kultūros paveldo vertybės teritorijos riba. Žvalgymų elektros kabelio tranšėjos vietoje metu buvo stebimi 63 m ilgio, apie 35 cm pločio ir iki 75 cm gylio tranšėjos kasimo darbai, tikrinamos iškastos žemės, surinkti pavieniai radiniai (bendras žvalgymų plotas-22,05 m²).

ENIn 2015, a field survey and evaluation were conducted on the grounds of Bobriškis old believers church, Rokiškis district. This church is directly connected with the beginnings of the history of the old believers in Lithuania. In 1710, the first old believers prayer house located in Lithuania and known from historical sources was erected in nearby Puščia (Girelė) village. In 1819, it was moved to Bobriškis village. The precise construction date of the present church building is unknown. When the persecution of the old believers increased in the Russian Empire in the 19th century, Bobriškis old believers church, which was in a remote location, was not closed and became one of the most important old believers centres in Aukštaitija. Three 2x1 m test pits were excavated and the earthwork in a 63 m long, roughly 35 cm wide, and up to 75 cm deep service trench (22.05 m²) was monitored. In test pits 1 and 2 and at many places in the monitored trench, a 15–25 cm thick, mixed 19th-20th century cultural layer with isolated finds was recorded. In test pit 3 and in the nearby segment of the ditch, a roughly 2,75 m wide and 70 cm deep storage pit created in the 19th century was recorded under the turf and the roughly 20 cm thick, mixed 19th-20th century cultural layer. It contained 17th/18th early 19th century finds: sherds of household pottery, metal artefacts, glass shards, charcoal, animal bones, and the rubble from a conjectured clay oven.
