Exeter Cathedral has stood at the heart of Devon for nearly a thousand years. Its Norman towers and Decorated Gothic interior are topped by the longest uninterrupted medieval stone vaulted ceiling in the world. Inside you can see the 15th-century Astronomical Clock and an early set of misericords, and guided floor tours and audio guides help bring the building to life.

Tip: Head for the Treasures Exhibition tour or a guided floor tour, both included in standard admission, though floor tours are subject to availability.

Forde Abbey is a former Cistercian monastery, now a family home, with nearly 900 years of history. Inside, you can see surviving monastic parts such as the cloisters, the monks' dormitory and the old chapter house, alongside State Rooms with ornate plaster ceilings and four-poster beds. The house is also known for its Mortlake tapestries, woven from the famous Raphael cartoons.

Tip: Dogs are welcome in the gardens on a short lead, and the nursery and gift shop can be visited without an admission ticket.

Lyme Regis Museum overlooks Lyme Bay and the Jurassic Coast, and it is built on the site of the former home and fossil shop of Mary Anning. Three galleries tell the story of the town across 200 million years, using objects, audio and touchscreens, with plenty of interactive and touch exhibits.

Tip: If you're visiting with children, ask for the Museum Trail at Reception, which comes with the admission ticket.

Montacute House is a late Elizabethan mansion in South Somerset, completed around 1601 and built of golden local Ham Hill stone.

Tip: Parking is free, and timed entry tickets are used on busier days, so check before you set off. The Ladies' Walk is a 45-minute climb with lovely views over the village.

Otterton Mill is a working watermill beside the River Otter, near Budleigh Salterton. A mill has stood here since the Domesday Book, and the old workings are free to look round, with a self-guided tour and the water wheel kept turning. Flour is still milled using traditional methods.

Tip: Well-behaved dogs on leads can sit outside or downstairs in the café, but only assistance dogs are allowed in the farm shop, gallery and upstairs café.

Tip: The main public entrance gates are in the village of Kenton, so head there rather than to the castle's other side.
