Auenstein Castle was built on a rocky hill above the Aare river in the 13th century for a local nobleman named Gowenstein. Around 1300 it was acquired by the Lord of Rinach. During a war between the Habsburgs and the Old Swiss Confederacy in 1389, a Bernese army sacked and burned the castle. Following the Bernese conquest of the Aargau in 1415, Auenstein became a part of the Landvogtei of Lenzburg. Over the following decades, the Lords of Rinach were not able to rebuild the castle and in 1465 Albrecht von Rinach sold the ruins and surrounding villages to Heinrich Hasfurter from Lucerne.
The castle remained ruined, but over the following centuries the ruined castle and the attached Herrschaft passed through several owners. In 1732 the castle and territory came under direct Bernese control and for the following half century it remained that way. Until the 1798 French invasion and the Helvetic Republic swept away the old medieval system of noble landlords who ruled over villages and estates. With the creation of the Canton of Aargau in the 1803 Act of Mediation the ruins became the property of the new canton.
In the 1850s the ruins were sold to a private owner who began building a new castle from the ruins. By 1858 there was once again a habitable castle on the site. The new castle was sold several times until in the early 20th century Mrs. A. Hoffmann acquired Auenstein. She renovated and expanded the castle and in 1927-29 it reached its current appearance. Today it is private use.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.
