Faniteum, Protected monastery in Hietzing, Austria

The Faniteum is a protected monastery in Hietzing that combines classical Renaissance features. The structure displays a central dome above a chapel, Corinthian columns in the arcade hall, and facades with loggias and columned passages.

Karl Graf Lanckoroński founded the Faniteum in memory of his second wife Franziska "Fani" von Attems-Heiligenkreuz (1861–1893), as a convalescent home for girls with a chapel intended as her mausoleum. The Swiss architect Emanuel La Roche built it from 1894 to 1896; Amand Louis Bauqué and Albert Emilio Pio remodelled and enlarged it in 1899. The Luftwaffe seized it in 1938, British occupation forces used it from 1945 to 1948, and the Discalced Carmelites bought it in 1974, establishing St. Josef's convent; Walter Hildebrand extended the two-winged complex into four wings in 1976–1977.

The chapel holds a stone relief of Italian origin from the early 16th century in the lunette above the main portal, aligned toward St. Stephen's Cathedral. A marble tombstone of the Lanckoroński family from the interwar period stands in a side room reached through a Venetian window. The corridor of the east wing has wall paintings of the Seven Corporal Works of Mercy, made by Wilhelm Steinhausen in 1895/1896.

The Faniteum stands on the Gemeindeberg in Ober-St.-Veit, at Hanschweg 1 near the St. Veiter Tor of the Lainzer Tiergarten, reached by the roads climbing the hill. The 19th-century wing faces the street with its loggia and pilaster arcades. As the convent of the Discalced Carmelites has been here since 1974, the enclosure is not open; visitors see the exterior only.

The chapel's arcaded porch with Corinthian columns faces the direction of St. Stephen's Cathedral, and its lunette holds an Italian stone relief carved in the early 16th century. The crypt beneath the domed central chapel holds the tomb of Franziska "Fani" von Attems-Heiligenkreuz, who died in 1893.
