While Googling for information on medieval city rights in Germany, I found this useful holiday information:

bq. The Pope’s Bavaria – Map and Information for Following in the Pope’s Footsteps

bq. Although Pope Benedict XVI didn’t have anything directly to do with the goings-on in Altotting, the town hosts one of Germany’s most celebrated shrines, the Chapel of Mercy. Altotting is Germany’s Lourdes, with the Chapel’s 13th century statue of the Blessed Virgin credited with numerous miracles. Altotting has been a place of pilgrimage in Germany for over 500 years.
