Würzburg is a Franconian city on the Main river built around the Würzburg Residence, a UNESCO-listed Baroque palace with a famous Tiepolo ceiling fresco, and the older Marienberg Fortress on the hill directly across the water.
Late spring through early autumn, when the vineyard terraces below Marienberg Fortress are green and evenings on the Old Main Bridge stay warm enough to linger with a glass of Franconian wine.
Try Franconian wine — specifically a dry Silvaner in the distinctive flat Bocksbeutel bottle — at a Weinstube near the Old Main Bridge, paired with Fränkische Bratwurst.
Stay in the old town within walking distance of the Residence and the Old Main Bridge, close enough to walk up to Marienberg Fortress in the morning.
Book the Residence's staircase and Tiepolo fresco as a guided or timed-entry visit in advance in summer — it's the single most-visited room in the palace and ticket lines back up fast.
