Three projects for archaeological excavations and five projects for conservation were realized by NI Stobi during 2011. Coordinator of all of the projects was Silvana Blaževska.

The excavations conducted at the House of Peristeria and the Western Necropolis in the period between April and August, were financed by the Macedonian Government as part of the major project for archaeological excavation of Stobi. The second phase of the conservation of the mosaic from the House of Peristeria was part of the same project. 

The excavations in the House of Peristeria were focused under the mosaic in the eastern triclinium. The bedding for the mosaic was documented at the beginning as well as the drainage and water supply system for the central fountain. Under the bedding, habitation layers from the 1^st – 3^rd century AD were excavated. The most interesting discovery was the pottery kiln from the 1^st century AD. Below the habitation layers part of a Hellenistic cemetery from the 3^rd/2^nd century BC was revealed. The four graves from the time of Phillip V and Perseus contained ceramic vessels, terracotta figurines, metal objects and an oil lamp. Judging by the pottery, the lowest layer which rested on the bedrock belonged to the Late Bronze Age and Transitional period (11^th/10^th century BC). The remains are modest, due to the later activities but they are fine evidence for the continuous habitation of Stobi since the prehistory. After reaching the bedrock the excavated soil was put back, consolidated and new bedding for the mosaic was placed.

24 graves were excavated at the Western Necropolis. Most interesting are the graves with rectangular mud brick construction and the grave with 34 terracotta figurines. Especially intriguing are the figurines of a soldier or a gladiator and the figurine with a male and female struggling over an amphora. These two depictions are discovered for the first time in Stobi.

Cleaning and retouch of the different parts were done during the second phase of the conservation of the mosaic from the House of Peristeria.  The activities took place in September and October. The end of the third phase i.e. placing back the mosaic in its original position is expected in the first half of 2012.

Besides the excavations, the conservation and restoration of the fountain in the triclinium was another activity in the House of Peristeria. This project was realized in October.

Funded by the US Ambassadors Fund for Cultural Preservation, the last stages of the project for conservation of the frescoes from the Episcopal Basilica were finished in the period between April and August. After the consolidation, attachment to honey comb panels, cleaning and retouch, the wall paintings are well conserved and prepared to be placed back in their original position. Before that, a temporary exhibition of the most interesting parts will be opened in 2012.

The collaboration with the Balkan Heritage Foundation from Bulgaria resulted in three different international projects: Workshop for Conservation Documentation and Restoration of Roman Pottery, Workshop for Fresco Conservation and Documentation and Archaeological field school. During the workshops in June, several roman vessels were conserved as well as small part of the frescoes from the eastern wall of the Old Episcopal Basilica. The excavations were conducted in the area of the 6^th century housing complex. In August and September, five rooms of a house from the second half of the 6^th century were investigated. Fragments of cooking and storage vessels, metal objects, bone objects and coins were the common finds.

At the same time with the field school, the unrevealed parts of the House with a triclinium were excavated. Trenches for documentation of the stratigraphy under the floor were placed at different places. 

At the end of the year, during the last two months, the walls of the House with a triclinium were conserved. This was the first phase of the project for conservation of the building while the second phase i.e. conservation of the floors will be conducted in 2012.
