Cascade

The Grade I listed Cascade has been a highlight of the Chatsworth Garden for more than three centuries.

The original design was completed in 1696 by Monsieur Grillet, a French hydraulics engineer who had worked on the waterworks of Louis XIV of France. Grillet's design was shorter and, in some ways, more complicated than the one we see today. 

The water flows over 24 steps that descend approximately 60 metres to mimic natural waterfalls. It takes advantage of the rainwater that drains from the east moors and collects in ponds on the hillside of the Derwent Valley within the Chatsworth Estate.

In 1702, the Cascade House, or Temple, was added at the top of the slope. Designed by Thomas Archer and featuring spouts, fountains and carvings by Samuel Watson and Henri Nadauld, the variation and flow of the water could be controlled from the Cascade House continuing the established tradition of water being used to surprise and delight visitors, one of whom in 1725 reported how jets within the building ‘throw up several streams and wett people’ (the spouts in the floor are still there).

The addition of the Cascade House was one of many alterations that have been made to the main water feature over the centuries.

In 1713, the Cascade underwent significant changes, doubling in length and becoming wider and steeper than the original. These changes were likely the 1st Duke's response to the increasing influence of French culture on grand formal garden design.

Further alterations were made between 1825 to 1828, when the Cascade was repositioned to align with the South transept of the house and a new gravel path was constructed up the slope.

It now forms part of a larger system of ornamental waterworks. Water from the moors above the house is fed down through the woodlands and garden, powering the Cascade and a hydroelectric turbine on its way to the river Derwent, in a feat of nature-based engineering. Water from the Cascade's lower pool directly feeds the 1st Duke's Sea Horse Fountain on Chatsworth's South Lawn.

Many of these changes, including the addition and removal of ornamental accessories such as statues, can be identified in historical illustrations of Chatsworth, such as those by Jan Siberechts and Kip and Knyff's engraving.

While the Cascade underwent some modifications in its early days, this was the result of evolving personal tastes and styles. However, as time went on, structural and design issues began to surface. By the early 1800s, it required frequent repairs and renovations.

Unfortunately, the construction of a coal tunnel beneath the Cascade in the 1830s to supply heat to the Great Conservatory, created further structural issues. The tunnel is no longer accessible to visitors due to serious damage caused by water seeping through the Cascade stonework and surrounding soil.
