The archaeological season of the year 2006 at Apolonia continued with the excavation of trenches M-N-O-P/28-30, intending to identify the cities portico. Initially the excavations continued following the surface stone line that was considered to be part of the portico foundation wall. In the most north-eastern part of the area a north south orientated wall was uncovered (US 406), which seems to have been lately integrated into the portico structure. The wall is interrupted at the southern extreme by a layer (US 412) which is rich in statuettes and colons fragments. The excavations in the trench P uncovered the foundation remains of a quadrangle plinth stone. The extension of the excavation toward the north enabled the discovery of the foundation portico wall (US 431) and the most eastern extreme of the apse (US 427). The wall seemed to have destroyed the apse, as it was an earlier construction. To the north US 427 was uncovered a wall (US 429), perpendicular to wall 406. The revealed structure did not suggest being part of the portico facade wall as they were partly covered by the demolishing layer (US 466). Excavations continued in the area between wall 406 and 431, intending to examine the stratigraphical sequence. The layer US 400 covered the walls 406 and 431. The other layer was labelled US 415 and the successor US 416. This latter was poor in archaeological material. Layer 423 might be chronologically related to wall 406. The lower layer 472, rich in archaic material was cut by wall 431. The portico level was not made visible suggesting in this way that the all the surface area has been ploughed after the destruction of the agora. The excavations in trench Q 44 revealed the foundation bed and a base from the façade columns. In trenches T 44 - 45 was uncovered the north-eastern corner of the portico which dates to the second half of the 2nd century B.C., or the beginning of the 1st century B.C. On the southern side of the plateau were excavated trenches B-C-D/38-39, revealing a wall which was seen at the bottom of hill 401. Afterwards trenches F38-39 were excavated but the inner part of the wall was not revealed. The excavation results showed that the upper part of the wall stays 1 m below the foundation level of the portico column, and these walls, possible are part of a series of terracing walls. Finally, trenches I-J/35-36 was excavated, uncovering a big basis and a mass of stones.
