The Sisi Chapel (German: Sisi-Kapelle) is a neo-Gothic chapel located in the Sievering area of the Viennese district of Döbling near the Vienna Woods (Wienerwald).The Sisi Chapel was built on the occasion of the marriage of Empress Elisabeth and Emperor Franz Joseph I of Austria on April 24, 1854, in Vienna. Johann Carl Freiherr von Sothen commissioned architect Johan A.
Garben to design the chapel and construct it in Am Himmel, a popular recreational area between the Sievering area (Döbling district) and the Vienna Woods. The chapel was intended to serve both as a memorial to the historic event and a gravesite for Freiherr von Sothen and his wife Franziska. The chapel was erected between 1854 and 1856 according to the plans of Garben by the city builder Josef Kastan. The chapel was consecrated to the patron saints of the Imperial couple on July 31, 1856: Saint Elisabeth, Saint Francis of Assisi, and Saint Joseph.
