There's a couple lying on a gentle slope opposite the Stonehenge circle and they're kissing like crazy people, entangled in each other as if the rest of the world has disappeared.

The situation is quite the opposite. This is Stonehenge and there are hordes of people everywhere. My friend Rob - our tour guide for the weekend's tour of Wiltshire - remarks that Stonehenge seems to be some sort of aphrodisiac. He's right. We have now seen three sets of lovers embracing on the ground near the historic monument.

What is it about the Neolithic site which has people feeling so amorous? It's a complete mystery to me, but then Rob had promised us the 'magical mystery tour of Wiltshire' which is his home county and a very mysterious place indeed.

Take Stonehenge for example. Obviously after hundreds of years of research, there are a few ideas about why the stone circle might exist. Some say it is a temple to the sun, which is why so many hippies (and non-hippies no doubt) flock to Stonehenge to celebrate the summer solstice.

But a stronger theory is the stones are ancient burial grounds, an idea supported by discoveries of cremation remnants. But what amazes me the most is that researchers estimate the 'construction process' of Stonehenge was between 3,000 and 6,500 years. Can you imagine generations of people keeping up the good work for that long?

Near Stonehenge is another Neolithic site called Avebury where stones are erected in a similar way but they are dispersed in a large field. It's the more exciting site to visit in my opinion because you can get right up to the stones.

Some idiots were too keen on etching their names in Stonehenge, so few people are allowed to get anywhere near the circle now. But in Avebury you're free to wander around and have a jolly good look which was much more exciting.

However, I have to admit that nothing Wiltshire has to offer thrills me more than Silbury Hill. This runs with the county's theme of placing strange things in the middle of fields. Rob drives us up to Silbury Hill and I immediately think we're going for a walk to see the beautiful Wiltshire countryside from up there.

But nobody is allowed to walk on Silbury Hill because it is another important ancient site - the largest man-made earth mound in Europe. It is 40 metres high and covers five acres of land but it looks quite unremarkable from the carpark, which only adds to its absurdity.

Researchers have undertaken several excavations of Silbury Hill and estimate the hill was constructed about 4750 years ago as a sundial, which they used to determine the length of seasons.

The truly amazing part is that the researchers also estimate 18 million hours of work went into creating Silbury Hill.  Imagine wanting to know the weather report that much. I'm going to be way more thankful for Jim Hickey when I get home to New Zealand!

Wiltshire is a fascinating county and our magical mystery tour of the area - while leaving us slightly baffled - has shown us England is a country full of quite an amazing history.

We are now itching to see more of what England has to offer, particularly if the tourist attractions are all as wonderfully weird as those found in Wiltshire.
