Closed complexes define every archaeological site since they deliver direct information about the everyday life of the prehistoric society at a certain place. For tell-sites the opportunity for reconstructing the past on the base of closed complexes is even better. Burnt houses are the best example. Following the settlement sequence, they can show differences in architecture plans, building techniques, pottery development, the distributions of various kinds of goods and so on. For that purpose, however, the crucial points are detailed documentation of the fieldwork and precise study of the archaeological material afterwards followed by complete publication. Unfortunately, there is scarcity of that kind of information for the late Eneolithic settlements in Bulgaria. In publications most of the archaeologists include only general results of their excavations without further details for certain features.

One of the bad examples is the Rousse settlement mound. The excavations on the site have a long and uneasy history. As a result of the four main archaeological campaigns (conducted in the period 1904-1990, with decades of breaks in-between) the site was completely excavated. Different goals and methodology applied in every campaign have caused lots of problems. A large amount of finds has been gathered but only in publications for the 1949-1953 campaign the finds are connected to a certain house.

The current study is an attempt for identifying burnt structures from the Rousse settlement mound and their ceramic complexes from the last campaign. It is achieved by comparing data for burnt house remains with presence of secondary burnt vessels on the same location. The study is focused on the 1986-1990 campaign since official documentation is available only for these years. Its main goal was the complete examination of the site whose height was 3.60 m at this point. Certain mistakes in fieldwork led to the mix-up of materials from different layers. More than 300 complete and restorable vessels were found but without context. Applying the mentioned secondary analysis, some of the field mistakes could be repaired and the vessels could finally find their places in the history of the Rousse settlement mound.
