Established from 1332 to 1339 as a foundation endowed by the wealthy patrician Konrad Groß for the elderly and needy. Considered the largest private endowment by any individual before 1500.
The Hospital of the Holy Spirit was established in 1332–39 by Konrad Gross, a wealthy patrician, for the care for the elderly and needy. It was the largest private endowment in the Holy Roman Empire up to 1500. After 1500 the building complex was extended over the Pegnitz according to plans by Hans Beheim the Elder. Two structures along the southern arm of the river and the north wall of the former hospital church with its polygonal ridge-turret survive.
From 1424 to 1796, the imperial regalia were kept in the hospital church (not reconstructed after the war). In the arcaded Kreuzigungshof, there are the central figures of Adam Kraft’s Crucifixion group (ca 1506/08) and the tomb monuments of Konrad Gross (d. 1356) and Herdegen Valzner (d. 1423).
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
