[3] The Duchess had originally expressed a desire to be buried in the mausoleum of her brother, Ernest I, Duke of Saxe-Coburg and Gotha, in the now Bavarian town of Coburg.

[5] The Duchess's body lay at St George's Chapel in Windsor before being interred in the mausoleum in a granite sarcophagus in August 1861.

[5] The Historic England listing describes the style of the mausoleum as "Heavy late French neo-classical.” It is made from Portland stone with a ribbed dome in copper surmounted by a balustrade.

The rotunda structure is surrounded by 16 Ionic 10 ft tall columns, made from Cornish granite from Penryn with bronze capitals and bases.

[8][1] The main approach to the mausoleum faces a bridge over a lake with a double flight of balustraded steps.
