Kaiser Friedrich III Mausoleum

The structure holding the final resting place of the German emperor was added to the north side of the Protestant Church of Peace (Friedenskirche) located in Potsdam's Sanssouci Park between 1888 and 1890. The architect was Julius Raschdorff, who also designed the Berlin Dom (Cathedral) and Reichsburg Castle, the latter which also had Salviati mosaic decorations.

The cupola of the High Italian Renaissance style mausoleum can be seen to the right of the church itself.

Friedrich's sarcophagus is located in the middle of the rotunda, alongside that of his wife Empress Victoria. As the eldest daughter of Queen Victoria, she was the former Princess Royal of Great Britain and Ireland. The tombs of two of their young sons are also interred here.

Salviati adorned the tomb with mosaics, including those on the wall showing "VRI" for Victoria Regina Imperatrix, which are now missing. As seen from the recent picture above, compared to the interior in 1931 the entire lower level has been refaced in black marble. The interior of the dome is still said to contain the mosaics of alternating angels and palm trees; however, entrance to the mausoleum is restricted and no photographs have been found.

Reichsburg Castle

Overlooking the Mosel River and located about halfway between Frankfurt and Aachen, the original 11th century castle was burned down by invading French troops in 1689. However, it was rebuilt in the neo-Gothic style by Berlin businessman Louis Ravene in 1868, under the direction of Julius Carl Raschdorff, architect of the Berlin Cathedral. The castle was used as the Ravene family's summer residence for almost 100 years.

Salviati decorated the castle's tower with a 300 square foot mural of St. Christopher, who is carrying the Christ child on his shoulder.

Today, the town of Cochem owns the castle and it is a popular tourist attraction.

Update: Per Cochem Castle, the tower and the original mosaic were destroyed in World War II. A reproduction of the Salviati mosaic was installed in the 1960s.
