The excavations of the Polish Archaeological Mission at the site of Marina el-Alamein took place from March 7 to April 11, 2005.1 The team focused its activities on further excavations of the architecture around the main square (forum) in the central part of the site (for a map of the site, see reports in earlier volumes of PAM). The shops in the southeastern corner of the square, uncovered last year, were now completely excavated and the trench moved eastwards to uncover more rooms. On the other side of an alley that runs alongside these shops to the south, the complex of the civic basilica was explored still further, uncovering a passage to the west with an important inscription. Concurrently, explorations continued of the mausoleum-hypogeum Tomb 21, uncovering the main burial chamber, as well as doing additional work on the collapsed façade of the mausoleum. The work in this tomb remains to be completed. A full anthropological study of the skeletal remains from the main burial chamber of Tomb 21, as well as from Tombs 29 and 30, excavated in the previous season is reported on in the Appendix to this report.
