These concrete obstacles were constructed from 1941 during the Second World War and were intended impede the movement of invading German tanks and other armoured vehicles. They constitute perhaps the best surviving example of dragon’s teeth emplacement in Surrey. They are so well preserved that some people even wonder if they are post-war imitations created for TV or a film programme! These defences descend the slope through Thorneycroft Wood to the edge of a channel of the River Wey. They comprise five rows of dragon’s teeth which take the form of flat-topped pyramids made of reinforced concrete. Some of these pyramids are capped by jagged bits of metal that would have supported wire tangles to obstruct passage between and over the dragon’s teeth. Nearby there are also at least three rifle pits formed with cement-filled sandbags.

The Sandpit on Horsell Common is arguably the Common’s most popular and interesting feature! This tranquil beauty-spot is a particular favourite with children, dog walkers and photographers. Historically the Sandpit was excavated for many years for sand and gravel to supply building materials. However, the site is best known as being the location where the Martians first landed in the famous 1897 science fiction novel “The War of the Worlds” by H. G. Wells. When he wrote this work Wells was living in Woking just a mile and a half away so this proximity doubtless influenced his choice of the Sandpit for the first Martian landing.

A short stroll from the Pavillion, the Cascade is a 30-foot (9 m) waterfall. Created in 1789, its presence relies on a decent amount of rain and it’s at its most impressive after prolonged, heavy rainfall. Just a little bit further along the trail are the Leptis Magna Ruins, which were built from masonry recovered from an ancient Roman city that existed in what is today Libya.

The Cascade, or Waterfall, is also notable. It is close by the A30 main road and constructed from stones brought from Bagshot Heath. They are rumoured to be the remains from a Saxon settlement. From the Cascade a stream runs through a glen and ultimately enters the Thames at Chertsey. By the side of the Cascade, immense stones are arranged to form a cavern known as 'The Robber's Cave'. http://www.thamesweb.co.uk/windsor/info/grtpk.html#anchor445739
