Dâmboviţa, day and night

The river in Bucharest is Dâmboviţa. According to studies, its name comes from Slavonic and means "oak-tree leaf", but the legend says this was the name of a beautiful girl that enticed the shepherd named Bucur and made him build a small settlement here.
A folk song says: "Dâmboviţa, you sweet water, he who drinks you leaves here no more". The river creates a series of lakes on its way through the town, like a string of beads, and parks were born around most of them. Seagulls have found shelter on the lakes and even on the river itself, which is really strange because the sea is 300 kilometers away. They just came for winter and never left again.
Maybe the song is true, after all.
