It is possible to express the top cover construction with the cornices made by carving the bedrock at the point where the side walls intersect with the top cover, sometimes in a single row, sometimes in two rows. It is doubtless that in Urartian architecture, the upper cover of the buildings was created with wooden logs / timbers lined up side by side. The building structure was most likely represented by the moldings in these tombs. This arrangement is seen in the Inner Castle Tomb and the main hall of the Eastern Rooms. In the Neft Well Grave, the cornice formed with two rows of half-round rows appears with a different understanding in the main hall and the burial chamber no. Cornices in the Neft Kuyu burial chamber, at the entrance of the II. It closely resembles the applications in the Mazgirt-Kaleköy rock tomb with an inscription belonging to Rusa. At this point, Neft Well Grave and II. It should be argued that there may be a chronological link between the Rusa period.
The application of niche can also be seen in royal tombs, rock tombs in rural areas and underground carved graves in Urartu geography. In the Van Castle Argişti Tomb, Tutak / Atabindi tomb, very small niches are lined up along the grave wall. In Palu tomb number 3, niches of the same size attract attention. There are also niches in the rock tomb in Iran / Sangar. In addition, niche applications are common in Altıntepe and Kalecik underground carved graves just northeast of Van Castle.
The chronology of the burial chambers is highly controversial. Except for the Great Horhor Tomb, on which the annals of I. Argishti are written and therefore dated to him, there are no graves that can be dated and evaluated on the basis of style criticism or advanced architectural workmanship. However, the style criticism and the dating based on the architectural development and location of the tombs bring some controversy within itself. For example, II because of its location. In the Eastern Tomb dated to Sarduri, I, who adopted the same tradition with his father, especially at the point of written tradition, was the son of Argishti II. Why Sarduri does not have an inscription. Again, writing long inscriptions in the royal cities, where writing was used most often and important developments were recorded in the architecture and many other points of Urartu. Why is there no inscription in Rusa’s possible burial chamber? If we are going to date it due to the location of the Founders’ Tomb, which is claimed to belong to the founding kings Sarduri I, Ishpuini or Minua because they are located in the ditch and are under the upper citadel, except for the ditch that is dated to Sarduri I with the inscription on it, even outside the city wall, Wouldn’t the dating criteria of the Sardur Bastion structure built on the plain floor be questioned? Because the early structures in the Van citadel must have been located between the ditches, the spreading of the structures outside the trench with the expansion of the citadel has been accepted as an important criterion in dating the structures in the citadel. It is possible to increase the number of these contradictions at the point of dating the burial chambers. Unfortunately, archaeological and philological data obtained to date make it difficult to assume which tomb could belong to which king. In fact, the chronology of the Great Horhor cave, on which only the political activities of Argishti I took place, can be evaluated in the same context. In Van Castle, Minua Shirsini, which is in the form of a large hall carved into the bedrock, dated to the Minua Period due to its inscription on its entrance, has parallels with the tombs in terms of construction technique and understanding.
