New archaeological excavations have led to the discovery of an intact six metre-high stone column. The column probably came from the Roman site of Lousonna (perhaps from a public building such as a temple or basilica, or from a wealthy private residence), but appears to have been transported here in the Medieval period to be recycled (as the presence of a nearby lime kiln would suggest).

To enable work to progress as quickly as possible, extra teams were drafted in so that construction could continue during the night for a number of weeks.
