Herford Abbey was the oldest women's religious house in the Duchy of Saxony. It was founded as a house of secular canonesses in 789, but moved later to the present site. The city of Herford grew up on this site around the abbey. The abbey was dedicated in 832 and was elevated to the status of a Reichsabtei ('Imperial abbey') under Emperor Louis the Pious (d. 840).
Between 919 and 924 Herford was destroyed by Hungarians but was rebuilt by 927. In 1147 the abbey, which by this time had almost 850 estates and farms, was granted Imperial immediacy. This made it an independent territory within the Holy Roman Empire which lasted until 1803.
In 1533, during the Reformation, Herford Abbey became Lutheran, under the Electors of Brandenburg. From 1649 for over a century the abbesses were all Calvinist but that did not alter the Lutheran character of the principality.
In 1802 the abbey was dissolved in the course of secularisation. In 1804 it was turned into a collegiate foundation for men, and in 1810 finally suppressed. The former abbey church remains in use as Herford Minster (Herforder Münster). The church is a late Romanesque hall church, built about 1220-1250. It is one of the earliest hall churches in Germany.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
