Franciscan Church
The Franciscan Chapel and Monestary are apparently amongst the oldest remaining buildings in Plzeň dating from the 13th century which means they survived both the Hussite and Thirty Years wars.

My 1985 guide of Plzeň (I really should try and find a more up-to-date reference!) labels the chapel seen in these photographs as Nanabevzetà Panny Marie which seems to translate as The Assumption of the Virgin Mary.
I don’t really understand religeous matters and so would refer you to the University’s page which details the history of the Franciscan Church.

During my visits to Plzeň the church and monestary weren’t open to the public as far as I remember however I believe they have now been restored and visits are possible.
