Archaeological digs carried out this summer on the site of the Roman-era public baths in the Bulgarian city of Bourgas have found the first frigidarium – a cold-water pool – that was part of the the Aqua Calidae baths.
The digs are part of a conservation and restoration project by the Bourgas municipality, meant to turn the Aqua Calidae – Thermopolis site, which housed public baths during the Roman, Byzantine and Ottoman eras, into a tourist attraction, the city hall said.
Found at a depth of about 4.6 metres underground, it has a length of 6.8 metres and is 6.4 metres wide. It had a brick floor that in some place did not stand the test of time and architectural features that have led archaeologists to believe that it was built in the second century CE, when the first public baths were built on the site by Roman authorities.
A frigidarium was the last pool that bathers would enter in the Roman baths (after the tepidarium and caldarium) and its temperature was kept cold to close skin pores.
The frigidarium in the Aqua Calidae was in the eastern part of the baths, which has been the focus of this summer’s digs under the supervision of professor Dimcho Momchilov, with archaeologists from the Bourgas and Yambol history museums joined by students from four Bulgarian universities.
The most significant finds of the season were 18 wooden combs, which appeared to have been preserved by the water in which they were found. The dig team believes that the combs date to the early medieval era, but required further study, given that construction of the Ottoman-era baths in the 16th century and the modern baths at the start of the 20th century caused some displacement.
Other finds included about 50 coins from the Roman, Byzantine and Ottoman eras, a golden ear-ring and a silver medallion, as well as other well-preserved wooden items.
