San Stefano Rotondo. The edifice was consecrated by Pope Simplicius between 468 and 483. The church was the first in Rome to have a circular plan, inspired by the Church of the Holy Sepulchre in Jerusalem.
The Heilbronner Portal in Friedenskirche (Church of Peace, Potsdam, Germany) leads from the cloister area to the Maryl Garden. It is a replica of a Romanesque portal at the Heilsbronn monastery in Franconia. The church is part of the palace grounds of Sanssouci Park under the patronnage of King Frederick William IV.
Santi Quattro Coronati interior, a hidden gem. This trip is shaping up to be focused on the spooky and the medieval ... and, as always, food and drink. Lots of food and drink. Fortunately, all the walking burns it off!
