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.

Grime's Graves is a large Neolithic flint mining complex in Norfolk, 8 km north east of Brandon. Miners worked here from around 2600 to 2300 BC, digging shafts into the chalk to reach seams of flint, which was much in demand for making polished stone axes. Some of the largest shafts are more than 14 m deep and 12 m wide at the surface.

Tip: Pre-booking tickets online gets you the best price for entry, and a free digital guide is available to help you explore the castle and its collections.

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.

IWM Duxford is a branch of the Imperial War Museum, set on the historic Duxford Aerodrome in Cambridgeshire. The site began as a Royal Flying Corps training aerodrome, played a prominent part in the Battle of Britain, and stayed an active RAF airfield until 1961.

Tip: Check the IWM Duxford website before you go for air shows and special events, as the site hosts them regularly.

Framlingham Castle is a Norman-era castle in the Suffolk market town of Framlingham, now looked after by English Heritage. Its curtain wall has thirteen towers and no central keep, and you can follow the wall-top walk right round the defences. Panels point out the town, the outer earthworks and the Mere, and the tall Tudor chimneys on the towers each have a different brick design.

Tip: Book advance tickets online to save money on the gate price, and pick up the free audio guide to get more from the wall walk.
