Tourism in the Khan Krum village area is characterized by two main attractions. And they are the Khankrum rock monastery and the Aul of Khan Omurtag.
Khankrum Rock Monastery
On the western slope of Kaluger Boaz (Kalugerska skala, Kaluger-kanara-duzyu) there is a rock monastery known as „Khankrumovsky rock monastery" (Kalugerska cave, Stalbenata cave, Merdevenli maara, Zapetaikata). Kalugera Cave forms the main part of the complex above Khan Krum. Steep steps cut into the rock lead to the monastery. Because of this feature, it is also called the Stair Cave. A natural cave was used, which was further adapted and finished in the 12th-14th centuries by hermit monks. The temple is artfully and precisely carved right into the rock.
The entrance to the cave faces south. From it you get into a vast cave. It has three rooms, one of which is a rock church with a well-shaped altar. Local residents have placed icons and niches are covered with cloths.
The first explorer of the Kaluga cave was the Czech explorer Karel Shkorpil (1895-1944). He also makes the first sketch of the cave. According to him, the Khankrum rock monastery is connected with the development of Hesychasm, a religious teaching that preaches pure "Christianity", the need for union between man and God in hermitage and silence.
The aul of Khan Omurtag
Near the village, a proto-Bulgarian palace (Aul of Khan Omurtag) was discovered, the construction of which refers to the construction activity of Khan Omurtag, based on the Chatalar inscription. From the inscriptions on the so-called Chatalar Column, found in 1905 at Khan Krum station, scientists first learned about the existence of Omurtagov aul. However, its remains were discovered only in the 1950s. The aul is located in the "Hisar Kale" area, in the territory of the Veliki Preslav municipality, about 2 km south of the village of Khan Krum and the Kamchia river, and about 10 km from the cities Shumen and Veliki Preslav.
The aul was built in 822 during the reign of Khan Omurtag. Built on the model of the capital of the first Bulgarian state, Pliska, the aul is an architectural work of the Pliskov-Preslav culture.
The aul was built on a sloping terrace a few hundred meters from right bank of Ticha river (today Kamchia) and a hundred meters from a Slavic population that arose on the ruins of early Byzantine cult center. The aul was fortified by a ditch and an earth rampart. An inner one was erected in the middle fortress wall of hewn stone blocks. The stone fortress had one main and one secondary gate, but without towers on the corners and walls, like other proto-Bulgarian fortresses. Similar in plan is only the strengthening of the palace complex (citadel) in Pliska. In the Omurtago aul, as in the Citadel in Pliska there was a small palace with a bath, but were also built here barracks for the inn's many guards.
The stone inscription on the Chatalar column indicates that this fortification was intended for the deployment of military units "against the Greeks and Slavs". It is probably an invasion of Byzantium in connection with the intervention of Khan Omurtag in the civil war between Emperor Michael II and Thomas the Slav.
