Varna is a city with a very long history. It is known that the city was founded in 570 BC by Greek colonialist navigators as a trading colony on the site of an ancient Thracian settlement. The name was given to him by Odessos, i.e. "the city on the water". In the 15th year BC, these lands were captured by the Romans and joined the Roman Empire. The "Roman period" began in Odessos, the first two hundred years of which were very successful for the city - the Romans fortified the city, built a water supply system, many temples and public buildings, including public baths (thermae)
That's what we're talking about, the largest public Roman buildings.
The baths were huge, they were full of life, the Romans were here every day and these structures were advanced)))Studies have shown that they were built by the end of the II - beginning of the III century and operated until the end of the III century.
And here you have boilers and water pipes and beauty in general made of marble.
From the point of view of that historical era, they deserve respect - broadly, on a grand scale, if you imagine - that's how many people there could have been... At the moment, modern man will see only ruins, ordinary such ancient ruins
