Experimental Research on the Compressive Strength of Masonry Repairs in Acheiropoietus Church, Thess

The Acheiropoietus timber roofed basilica is the best preserved early Christian basilica in Greece and the east Mediterranean coast lands. In its present state the monument (Figl) preserves five major periods of construction, which include early remodelling, followed by repairs due to strong earthquakes, as well as late modifications and modem reconstructions:
- erection of the basilica (5th century, phase A)
- remodelling of the staircase and south entrance portico and additions at the north and east side (7th century, phase B)
- extensive repairs of the church due to strong earthquakes which have also destroyed other buildings in the city (14th-15th century, phase C)
- post-Byzantine remodelling after the clerestory and the west gallery colonnades had been lost (beginning of the 20th century)
- extensive reconstruction of the south wall, the north and west gallery colonnades, at the beginning of the 20th century
