On 9th of September there is a special event “Day of open historical monument / Tag des offenen Denkmals Protected content Regensburg.
For more details take a look at the website (unfortunately as I have seen only in German language):
The event from the administration of Regensburg is always very great chance to visit a lot of historical monuments and museum in the city center of Regensburg.
And the best is: All events are entrance free.
