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 dam- age 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 occa- sionally. It was therefore decided to preserve the site in its current state in order to slow down the deterioration process and en- sure stability. This could only be achieved by backfilling it temporarily to provide a simi- lar environment to that where it lay for some 2000 years pri- or to its discovery, in order to avoid further loss of materi- al. 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 de- tailed analysis of the site, in the month prior to this interven- tion emergency conservation works were carried out by Her- itage Malta's conservatorres- torers. These included consolidation works, plastering of cracks and plant removal. Detached mosa- ic 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 rec- ognisable and reversible, en- abling 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 geo- textile. The Għajn Tuffieħa Ro- man Baths were discovered by accident in 1929, when work- ers were digging a trench to supply nearby fields with fresh water from a natural spring in the area. They informed Sir Temi Zammit, the Museums Direc- tor at the time, who excavated the site in 1929 and 1930 and who believed that the bathing complex dates back to the first or second century after Christ. The complex, whose location was probably chosen in or- der to fully exploit the natural source of water in the vicinity, consists of pools and cham- bers. One of the chambers was kept warm and is, in fact, ele- vated, resting on a number of arches where fire would heat up the water. Heritage Malta's Chief Executive Officer, Noel Zammit, said that this is a clear and practical example of how the national agency for cultur- al heritage gives a future to the nation's past. "The current situation was not allowing the site to be pre- served properly, leading us to decide to deprive ourselves of it in order to enable future generations to enjoy it instead. We cannot retrieve what has been lost from the site with the passage of time, but we can prevent further losses," said Mr Zammit, stressing that the backfilling is only a temporary measure and that Heritage Malta will not disregard this site but will continue to take care of its upkeep until the time comes for it to be uncovered again without any risk for the preservation of the site itself.
