Across the river, check out the Stalin-era statues. Legend has it Lithuanians left the statues up as a way to poke fun of the old Soviet regime. The statue photo apparently pays tribute to industry and construction according to the guide, though maybe it's education. Anyway, you go, Stalin--show respect for the workers by giving them statues while making their lives miserable!
The Green Bridge crosses the Neris River at Kalvariu g. The name is pretty self-explanatory (it's bright green), and the bridge itself isn't spectacularly beautiful or anything, but it does feature some of the last Soviet monuments / sculpture left standing in Vilnius. Go be inspired by the courage and work ethic of the 'heroic' farmers, soldiers, teachers, etc.... ;-)
This is the only place in Vilnius to see old style Soviet era statues. The four represent agriculture, industry, peace & youth.
