Lithuania, the Baltics' southern anchor, offers baroque Vilnius — a UNESCO old town of courtyards and church towers with a bohemian 'republic' inside it — plus the Curonian Spit's Sahara-like dunes between lagoon and sea, and a history that once stretched to the Black Sea.
Vilnius rewards wandering: Pilies street to the cathedral and Gediminas tower, the self-declared artists' republic of Užupis (it has its own whimsical constitution), and Europe's largest baroque old town. Trakai's island castle sits in lake country 30 minutes away; Kaunas brings interwar modernism; the Curonian Spit — shared with Kaliningrad — strings Nida's fishermen's cottages along colossal dunes, and the haunting Hill of Crosses stands near Šiauliai.
Medieval Lithuania was Europe's largest state, its Grand Duchy stretching to the Black Sea before union with Poland; the last corner of Europe to adopt Christianity keeps a pagan-tinged folklore. Between Soviet occupation and 1990 — when it led the USSR's breakup by declaring independence first — it preserved identity through song and basketball, the second religion. Lasers, fintech and food-tech now drive a fast-modernizing economy.
Vilnius's bohemian district across the river, which declared itself a tongue-in-cheek republic in 1997 — complete with a constitution on plaques in dozens of languages, an angel statue and April 1 'border' celebrations.
Yes — the UNESCO-listed dune peninsula (ferry from Klaipėda) feels like nowhere else on the Baltic: pine forests, giant sands at Parnidis dune, and Thomas Mann's summer house in Nida.
