The Premonstratensian Steingaden Abbey (aka "Welfenmünster") was founded in 1147 by Welf VI. son of "Henry the Black" and brother of "Henry the Proud". Welf VI was already a member of the "Younger House of Welf", as the "Older House of Welf" ended (male wise) with Welf III in 1055.

Welf III´s sister had married into the Italian d´Este family - and so she had started the "Younger House of Welf". The Welfs have been powerful counterparts to the Staufers - and the Welfs still exist - all over the place. One branch leads to George I of England, whose grand grand....daughter is Queen Elizabeth II. Other branches take you to the late Frederica, Queen of Greeks and mother of Queen Sofia of Spain - and of course, one line leads to Ernst August of Hanover married to the Princess of Hanover, aka Caroline of Monaco (daughter of Grace Kelly).

That is the thread leading from Steingaden - to London, Monaco and elsewhere. The abbey itself had a kind of volatile history. Over the first centuries, the buildings were altered from romanesque to gothic style - before they were burnt down and looted 1525 during the Peasant´s War. A couple of years later, it was rebuilt in the style of the Renaissance, to get burnt down again 1646 during the Thirty Year´s War. After a new start - now in baroque and rococo - it got secularized in 1803. Then most buildings of the abbey got demolished before the main church (the "Welfenmuenster") was turned into the parish church of the village of Steingaden.
