Vilnius

In Vilnius, the Grand Duchy's ancient capital is a wonderful treasure trove of medieval treasures and stunning Gothic and Russo-inspired Baroque architecture. Cobblestone streets swirl beneath the buttresses of the majestic St Anne's Church, over café-strewn plazas, and beneath the soaring Gediminas Keep and Upper Castle fortress dating from the 13th century in the Old Town.

Meanwhile, the new town's blocks buzz with beer bars and late-night rock clubs, and Europe's most famous boho district – the self-proclaimed Republic of Uzupis – beckons on the outskirts of town, with shabby-chic, graffiti-strewn streets and more drinking joints than you can shake a cepelinai potato dumpling at!

When the weather is pleasant in the evenings in Vilnius, the streets are lined with people sitting outside fashionable pubs and cafés. St. John's Church with a 60m high bell tower, with a blend of classical German Gothic, Italian and French Baroque, plus a Russian-style dome; surrounded by deep green hills.
