Structures on site provide shelter from sun and rain, however they offer no protection against heat, wind and water seeping beneath. Besides erosion caused by the elements, along the years damage has also been caused by small animals foraging in the area, plant roots, and people’s footsteps albeit the site is not open to the public except occasionally.
Plans for the conservation of the Roman Baths had been drafted for quite some time. In fact, two years ago, as a precautionary measure, a trial was conducted by backfilling a small area on site, devoid of Roman mosaic, with the same materials used in the latter intervention. Following a detailed analysis of the site, in the month prior to this intervention emergency conservation works were carried out by Heritage Malta’s restorers. These included consolidation works, plastering of cracks and plant removal. Detached mosaic pieces were put back in place so as not to be lost and so as to recreate the pattern. Every step was documented, including 3D modelling by Heritage Malta’s archaeologists.
The stratigraphy employed in the site’s backfilling is recognisable and reversible, enabling future archaeologists and conservator-restorers to distinguish the materials from the original site. Both local and imported materials were used. These were separated from the original surface and from each other through the use of geotextile.
