## About Lake Techirghiol

Lake Techirghiol is a former bay of the Black Sea, closed off by a narrow strip of sand that now holds the resorts of Eforie Nord and Eforie Sud; the town of Techirghiol spreads along its northern shore. Geographers call it a liman. It covers almost 11 km² and is no more than 9 m deep, which makes it the largest salt lake in the country. Because it receives very little fresh water, its salt content has risen to 80–95 grams per litre, depending on the source, so in winter the water can drop below 0 °C without freezing.

The lake is famous for the sapropelic mud on its bed, black and greasy, formed as the brine shrimp Artemia salina and the alga Cladophora decompose. On 4 July 1899 the Eforia Spitalelor Civile, the body running Bucharest's civil hospitals, opened the first organised spa establishment on the shore. Its successor, the Techirghiol Spa and Rehabilitation Sanatorium, still uses the lake's mud and water in treatments for rheumatic, neurological, gynaecological and skin conditions.

The lake has been a Ramsar site since 2006 and is a special protection area for birds. The Romanian Ornithological Society has counted 264 bird species in the area, because the lake lies on the Via Pontica, one of Europe's great migration routes.

### What you can see

On the Techirghiol shore, the lakeside promenade is a long walk of paths, lawns and benches, which the town hall uses for festivals in summer. In front of the sanatorium lie the Băile Reci (Cold Baths): a sandy beach with changing rooms and showers, where the cold mud is spread on the skin, left to dry in the sun and then washed off in the lake. From behind the promenade it is a few minutes' walk up to the Saint Mary Monastery, with an eighteenth-century wooden church brought from Transylvania.

In winter the lake draws waterbirds. The red-breasted goose, which breeds in Siberia and winters in Dobruja, spends the night on the unfrozen water; the globally threatened white-headed duck has also been recorded here.

### Good to know

The Băile Reci only operate in the warm season. The water is very salty: do not dive in and do not swallow it. The mud and the time in the sun are not for everyone, so if you have a chronic illness, ask a doctor first.

## Don't miss

- A mud cure at the Băile Reci in front of the sanatorium: the black mud, spread on the skin and dried in the sun, is then washed off in the salt water, where you float without effort.
- A walk along the lakeside promenade in Techirghiol, looking across the water to the blocks of Eforie Nord and the strip of sand that separates the lake from the sea.
- The Saint Mary Monastery, a few minutes from the promenade, with its arcaded eighteenth-century wooden church.
- The flocks of red-breasted geese that roost on the lake in winter, one of the rarest wild geese in the world.
