A marine lagoon thriving with life
Stjuža is the only marine lagoon in Slovenia. Its name originates from the Italian word “chiusa”,
meaning “closed”. It was formed by the river of Strunjan, which deposited sediments in its mouth.
After the embankment was built more than 400 years ago, the lagoon remained connected to the
sea only by the flow channel. There are no currents or larger waves in the lagoon and the water flow
depends completely on the low and high tide. As its average depth is approximately 0,5 m, the water
cools down and warms up very quickly.
