The dragon font.

The village of Haddenham has over 120 listed buildings, and most of them are made of an unusual material; Witchert.

Witchert was cheap and available. It could be dug up out of the ground just where you wanted to build, so it was used for all sorts of buildings and walls up to about 1920. Here are some of them.

The shortest version of this walk is slightly over half a mile, or 900m; good if you are not too mobile. The longest version is a mile and a quarter, or 2.6 km.

To get there, take the A418 South West from Aylesbury, and when you get near to the village, a couple of miles off the main road, follow signs for Tiggywinkles Wildlife Hospital. Keep on past the entrance to Tiggywinkles and park next to the green; there’s a pond.

You might see some Aylesbury ducks at the pond; they used to be bred in the village. This breed is easy to recognise. The plumage is white, the bill is pink, and the legs and feet are orange. They are quite large, especially compared to the other ducks I saw on the pond. Ducks with an orange bill are not Aylesbury ducks.

Haddenham has often been a location for film and television. Eleven episodes of Midsomer Murders have been filmed here, and when Kermit, Fozzie Bear and Gonzo parachute into England in The Great Muppet Caper, it’s this pond they end up in.

The church, at Whitchurch.

There’s more to the ancient village of Whitchurch than you might think, if you are just passing through. Amongst other things, hidden away are a secret World War 2 workshop, a castle, and a Tudor house that’s in disguise.

I parked on the High Street, facing towards Winslow, a little way North of the petrol station. I was right next to a post box. If you can’t find a spot there, try the side streets on the South (Aylesbury) end of the village.

Keep on the same side of the road and walk North towards the Winslow end of the High Street. There’s a long half timbered house on your left, just after the gentle left hand bend. This 16th Century house is now known as Winster Paddocks, but it was once a coaching inn called The Cock Inn, and from 1914 to 1989 It was a butcher’s shop.

The coat of arms on London Road Bridge is made from Coade stone, a ceramic material.

You might think that you know Buckingham very well, but here’s a few things you just might not know and can find on a walk that's just a mile and a half long.

Park at Cornwall’s Meadow. It has plenty of spaces and costs just 50p for three hours. It’s on the South side of the Stratford Road end of the High Street. From there, take the footpath through the woods at the opposite end from where you drove in. When you cross the footbridge over the River Great Ouse, turn right.

Walk past the skate park and playground, and you’ll find yourself at the end of London Road Bridge.

Built mostly at the expense of the Marquis of Buckingham, the bridge has his coat of arms in the centre of the North side, above the river arch. You might have seen it if you’ve walked across the footbridge that runs close alongside; it’s close enough to touch.
