The plaza below was created by clearing buildings damaged in WWII. The Marienkirche, on the left, dates to the 12th century, though it has been severely modified over the years.The pink pipes on the right are part of a system for removing groundwater that leaks into excavations. Berlin after all was built on a marsh.
The Marienkirche is still used as a church. Its rather plain interior reflects the Protestant tradition. The Evangelische church, the publicly supported merger of Lutheran and Calvinist churches, has services on Sunday mornings and the Anglican church uses it in the evenings.
Nearby the Nikolaivierteil is a pseudo-medieval area reconstructed under the DDR. It was once the center of the city. The Nikolaikirche for which the quarter is named was closed in 1939 for renovation, but reduced to a shell during the war. It has been restored, but is now in use as a city museum and for concerts. Many of the artifacts in the museum relate to its former life as a church.
The arches in the vaults are painted differently in various parts of the church. The nave is green and red. Two chapels on either side are blue and orange (we were told those are the colors of Mary). The chancel is gray and red.
Most reminders of the national socialists in Berlin have been deliberately obliterated. However, the Olympic Stadium, built for the 1936 Olympics is still in use as a sports and concert venue. A very fine roof has been added. The exterior facade is built of limestone rather than concrete.
Charlottenburg Palace is the largest palace in Berlin. It dates to the early 1700s and is named after the first queen of Prussia.
There are extensive gardens and a tame forest. In the back of the property is the Belvedere. A sign at the building indicated it was built as a private retreat for one of the kings. I guess you might call it his man-cave.
