Certain civic structures remain today, such as the Elbe-facing gallery of the Zwinger Palace complex. His first building for the Dresden Hoftheater burnt down, and the second, today called the Semperoper, was built in 1841. Other buildings also remain indelibly attached to his name, such as the Maternity Hospital, the Synagogue (destroyed during the Third Reich), the Oppenheim Palace, and the "Villa Rosa" built for the banker Martin Wilhelm Oppenheim. This last construction stands as a prototype of German villa architecture.
