The circular mausoleum was built for Constantia, daughter of the Emperor Constantine, in the early or mid-4th century and was consecrated as a church in 1254. After restoration work in the 16th and 19th centuries, apparently nothing now remains of the original mosaics of the dome. The sarcophagus drawn by Soane is now in the Vatican Museum and has been replaced by a copy (noted by Professor du Prey).Drawing 3 was identified as for the Church of Santa Constanza by Professor du Prey (January/February 2009).

Sir John Soane's collection includes some 30,000 architectural, design and topographical drawings which is a very important resource for scholars worldwide. His was the first architect’s collection to attempt to preserve the best in design for the architectural profession in the future, and it did so by assembling as exemplars surviving drawings by great Renaissance masters and by the leading architects in Britain in the 17th and 18th centuries and his near contemporaries such as Sir William Chambers, Robert Adam and George Dance the Younger. These drawings sit side by side with 9,000 drawings in Soane’s own hand or those of the pupils in his office, covering his early work as a student, his time in Italy and the drawings produced in the course of his architectural practice from 1780 until the 1830s.

Browse (via the vertical menu to the left) and search results for Drawings include a mixture of Concise catalogue records – drawn from an outline list of the collection – and fuller records where drawings have been catalogued in more detail (an ongoing process).
