LEGOLAND Windsor's Waterworks is a large 'water play' area in which young children can play with numerous interactive water features. Often full to bursting on a hot summer's day, the Waterworks are a great place for hyperactive kids to burn off some excess energy, whilst getting very wet!
If you plan to allow your kids free reign of this area, it might be worth considering bringing their swimming costumes.
In the early 2000's, LEGOLAND Windsor's Waterworks were updated to what can be seen today: a large water play area with geysers, sprinklers and plenty of opportunities to get drenched. The Waterworks they replaced, however, were arguably much more creative and unique. Take a look at these photographs from 1997...
Stretching right across the 'bottom' of the area was a large reservoir, which contained all manner of mechanical gizmos, from waterwheels to balances, and from tipping buckets to an Archimedes Screw. These could all be controlled from a variety of levers, buttons and wheels situated around the area.
The central island was mostly the same prior to the update, with wheels to turn and buttons to push situated around the model. During the refurbishment, a large central fountain was added to the top of this model, with jets which reach far outside the pool: whereas now the entire area is set aside as a 'wet' area, in those days there were distinct patches of 'wet', with a fairly good chance of people staying dry in between!
The Waterworks band was previously interactive, with the pressure pads that you can see below animating each of the characters, and playing their audio.
The pool towards the back of the Waterworks, like the central island, has also escaped much change: in 1997, as now, kids could aim water guns at a group of frogs and crocodiles, with direct hits resulting in a little victory hop from the frog, or a snap of the jaw from the crocodile.
