The settlement OHODEN-VALOGA is the first closed settlement complex found in Bulgaria dating back to the Monochrome phase of the Early Balkan Neolithic (6400-6300 BC). It could be synchronized with Protostarcevo phase of Neolithic culture found on the territory of Serbia. In 2002 was studied the first dugout house (among 10 registered during the spring expedition).
The pottery could find parallels in Divostin (Serbia), Koprivec and Poljanica (Bulgaria) and Otzaki Magula(Greece). Among the most interesting parts of findings discovered was the rich flint material with Mesolithic characteristics what raise again the problem of Neolithisation of SEE
During an international expedition research, conducted on the site of Ohoden in August 2002 the following major results were achieved.
1. A one layer settlement from the early Neolithic was discovered. The settlement is situated on the left bank of the river Skat on its' first non-flooded terrace.
2. The first dug-in settlement from the early Neolithic was discovered and partially studied.
3. For the first time in the region were discovered also miniature, well-processed flint tools typical for this period.
4. The architectural structures and materials discovered have no parallels in the northwestern region of Bulgaria.
5. The comparative analysis of the archaeological structure and the materials found shows that this is the first site in the region, which can be dated earlier to the Neolithic culture already known in this region. The materials can be attributed to the monochrome phase of the early Neolithic ceramic complex.
The scientific discoveries are also contributing to the clarification of the problem for the settlement of the Balkan peninsula of the first farmers more then 9000 years ago.
