This magnificent palace emerged from the buildings of the former Benedictine monastery of St. Emmeram. In connection with the abolition of the postal rights the royal house of Thurn and Taxis purchased the greatest part of the monastery buildings in 1810 and extended them to make them their permanent residence. https://tourismus.regensburg.de/en/about-regensburg/sightseeing/more-sights-to-explore/architectural-monuments/thurn-and-taxis-palace.html
