Ely Cathedral stands above the flat Fenland landscape, which is why locals call it "the ship of the Fens". The earliest parts of the present building date to 1083, and it is one of the largest Norman churches built in its day. Its nave is among the longest in Britain, and the central Octagon, with its lantern above, creates a remarkable space inside.

Tip: Book tickets and tours in advance, as tour places are limited, and check opening times first because it is a busy working cathedral.

Sandringham House is a royal country house on a large estate in the Norfolk Coast Area of Outstanding Natural Beauty. It is owned personally by the monarch rather than the Crown, and the house is Grade II* listed. The landscaped gardens, park and woodlands are on the National Register of Historic Parks and Gardens, and the site has a history stretching back to Elizabethan times.

Tip: If you're bringing a dog, check the estate's dog-friendly areas on its website before you set off.

Oxburgh Hall is a moated medieval manor house near Swaffham, with Victorian Gothic interiors. It was built in the 1480s for the Bedingfeld family, who still live in private apartments there. You cross the moat to a tall brick gatehouse, then explore the hall, which has a priest hole and needlework hangings worked by Mary, Queen of Scots and Bess of Hardwick.

Tip: Parking is free on site, and the hall is about 250 metres from the main car park along a flat gravel path.

Denny Abbey is a 12th-century, Grade I listed former monastery that was home in turn to monks, Knights Templar and Franciscan nuns, before becoming a farm.

Tip: The site closes each winter and on some weekdays, so check the current opening season and days on the museum's website before you set off. Parking at the entrance is free.

Peckover House is a Georgian merchant's townhouse in Wisbech, built in 1722 and home to the Quaker Peckover banking family for 150 years.

Tip: The house and garden keep different opening days, so check the National Trust page before you set off. Parking is in town, with Chapel Road the nearest car park.
