Tonge has an interesting history, long before the Mill you can see near GZ Tonge got it's name.
Around 450AD in recognition to military aid given to Britain by the Saxons, Vortigern, King of Britain granted Hengist, a victor over the Scots and Picts, as much land as he could cover with an Ox hide. Hengist was clever, and cut his hide into strips, or thongs, and laid them end to end to encircle 80 acres. This land was called Thwang or Thong and the name has evolved over the years to Tonge as it is now.
The pond you can see used to form part of a castle defence system, the castle has now been demolished, and the lake was was later used to power a mill. There has been a mill in Tonge for over 900 years, although the current version was built in 1837. Milling at the older building then ceased and the gears and water wheel were removed. This old mill building became a cake bakery.
Also near GZ is an area of green named Memorial Way, where you can sit on park benches, read plaques, signs and enscriptions. There is an information plaque detailing more about the castle and mill near the pond. On the pond there are usually ducks and other birds, who enjoy being fed, and memorial way would make a lovely place to stop off for a picnic yourselves.
