Rusenski Lom Nature Park (Bulgarian: Природен парк Русенски Лом) is a protected area in Ivanovo Municipality, Ruse Province, northern Bulgaria. The park was established on 26 February 1970, in order to protect the canyon of the Rusenski Lom, the last significant right tributary of the Danube. The park covers an area of 3,408 hectares (13.16 sq mi).The area of the park was settled in the prehistory. Between the 12th and the 14th centuries, during the Second Bulgarian Empire, the area became attractive for monks and several cave monasteries were founded. As a result of this, it became a significant cultural center. After the Ottoman Empire conquered the area, they started to decay. The remains of the monasteries are now a part of the Rock-hewn Churches of Ivanovo World Heritage Site located inside the park.
