Lake Bled is a glacial lake in which European country?

Lake Bled is a lake in the Julian Alps of the Upper Carniolan region of northwestern Slovenia, where it adjoins the town of Bled. The lake is 35 km (22 mi) from Ljubljana International Airport and 55 km (34 mi) from the capital city, Ljubljana.

The lake is of mixed glacial and tectonic origin. It is 2,120 m (6,960 ft) long and 1,380 m (4,530 ft) wide, with a maximum depth of 29.5 m (97 ft), and it has a small island. The lake lies in a picturesque environment, surrounded by mountains and forests. Medieval Bled Castle stands above the lake on the north shore and has a museum. The Zaka Valley lies at the west end of the lake.

For centuries, Europeans have flocked to the shores of Lake Bled to enjoy recreation, but also the medicinal benefits. Emperor Henry II, ruler of the Holy Roman Empire enjoyed the lake so much, but he also built Bled Castle in 1004 to confer it as an estate. Today the castle is a popular tourist attraction.

The World Rowing Championships in 1966, 1979, 1989, and 2011 were held at Lake Bled.
