Techirghiol Lake or "Techir Lake"

     Techirghiol Liman, also called Techirghiol Lake, is located on the outskirts of the seaside resort of Eforie Nord on the Black Sea shore, 12 km away from Constanta port, Romania. It is a fluvio-marine liman with an area of ​​10.68 km², separated by the sea through a perisip and with a maximum depth of 9 m. By the small contribution of fresh water, the water of the liman has increased its salt concentration, to approx. 95 g / l. This phenomenon allowed the formation of a sludge layer with therapeutic qualities.


On the banks of the river opposite Eforie Nord is the town of Techirghiol, founded in 1893. A sanatorium has been opened in Techirghiol since 1899. The town is a famous treatment station, where the therapeutic effects of salted (mineralized) water and sludge from liman, recommended for the treatment of diseases such as psoriasis, rheumatism, allergies, etc.

An overview of the chemical composition of the lake indicates a central portion, comprising the Techirghiol, Eforie Nord and Eforie Sud stations, a practically homogeneous mineralization and salinity, both horizontally and vertically (up to 3 m depth), in around 85.5 g at ‰.


The water and mud of Lake Techirghiol, therapeutic factors of great medical and scientific value, have been the subject of numerous studies, in the most diverse fields of research.


From the point of view of origin, Lake Techirghiol is a former lagoon of the Black Sea, today completely separated from it, the complete disruption of the connection with the sea being relatively recent. The lake is 1.5 m below the Black Sea level, has a variable depth from 0.5 m to 5 m, sometimes reaching 9-10 m. The fauna consists of several species of arthropods, worms and protozoa, flora by some species of algae, and towards the bottom the colorless and colored sulfurous bacteria predominate. Glossy and unctuous, the mud in Lake Techirghiol is black as it is black and has a characteristic odor. It possesses physico-chemical properties that make it extremely useful in the treatment of various diseases along with saline water.


The legend of Techirghiol Lake is told from generation to generation and is the basis of the recognition of the benefits offered by salt water and sapropelic sludge at national and international level.


It is said that an old Tatar blind and blind by the name of Tekir arrived with his wounded donkey at the shore of this lake, where the animal entered to bathe. The old man struggled then for hours to get him out of the smelly mud, but the stubborn donkey didn't want to move out of the water. Great was the wonder and joy of the old man when, coming out of the lake, he realized that his eyes could distinguish the light again, and his long, helpless feet had begun to listen to him. As for his wise ass - the wounds on his back had healed, and his body seemed to be living a new youth. Upon hearing the news of this miraculous event, people came to the lake, bathing and anointing themselves with mud to find their cure. And because Tekir and his donkey were the ones who discovered the miraculous benefits of the lake, it was called Techirghiol meaning "Techir's Lake".


The first written testimonies about the use of mud and baths in Lake Techirghiol for healing purpose date from the 1800s, and in 2014 115 years of recognition of Lake Techirghiol in balneology and its therapeutic properties were celebrated.
