St Davids holds city status thanks to its magnificent 12th-century cathedral, Britain's smallest city with a population of less than 2,000. The cathedral sits in a hollow, its purple-hued stone tower invisible from a distance, creating a dramatic reveal as you approach. The ruins of the medieval Bishop's Palace stand beside it, while the tiny city has excellent galleries, shops, and restaurants. Stunning coastal scenery surrounds St Davids, including the dramatic Pembrokeshire Coast Path, beautiful beaches, and opportunities to see seals, dolphins, and seabirds.
