About Tallinn
Tallinn is Estonia's capital and the Baltics' postcard — medieval old town (UNESCO site), city walls, and a vibe that's part fairy tale, part tech hub (Skype was invented here). It's touristy but earned it. The city is tiny (half a day to see everything), but the food scene and nightlife are solid.
