Grotto In The Grounds Of Ascot Place, To South Of House At West End Of Lake

This grotto, built around 1750, is located within the grounds of Ascot Place, to the south of the main house and at the western end of the lake. It was commissioned by Daniel Agace and constructed by masons Robert Turnbull and Scott. The materials used include stone, embellished with clusters of glittering quartz crystals and other exotic minerals.

The grotto has an irregular plan consisting of a central main chamber connected to several smaller chambers. Access is gained by approaching a mound composed of large boulders and blocks, partially concealed by grass, mosses, and shrubs; two flights of irregular stone steps lead to the summit, where flat stones provide seating. Below the rocky entrance, there is an iron gate leading to a small antechamber with seats formed from low rocks and quartz decorations on the walls. A narrow, quatrefoil-shaped entrance leads to the main chamber, which is lit by an octagonal lantern in the roof with leaded lights displaying quatrefoil patterns. The walls of the main chamber are extensively covered in clusters of small, white, glittering quartz crystals. Artificial stalactites, of varying lengths in a staggered double row, descend from the roof edges along with lengthwise crystals. Smaller passages and chambers are accessible via subsidiary entrances on either side of the main chamber.

According to contemporary accounts, the grotto was designed by Daniel Agace. Robert Turnbull is also credited with constructing the nearby Corinthian Temple, and the interior embellishment may have been undertaken by Joseph and Josiah Lane, specialist grotto builders known for their work at Oatlands and Painshill. The grotto is considered by some to be among the finest in Britain, and is a remarkable example of a Rococo garden structure, reflecting a taste for buildings that evoke mystery, delight, and a sense of natural wonder. It is part of the garden which is listed on the Register of Parks and Gardens of Special Historic Interest in England.
