The Neue Kirche (colloquially Deutscher Dom) was originally built in the 1701-1708 by Giovanni Simonetti after a design of Martin Grünberg. It was the third church in Friedrichstadt, established in 1688, which was a town of princely domination, while the neighbouring old Berlin and Cölln were cities of town privileges. The Prince-Elector originally only provided for a Calvinist congregation, since they - the Hohenzollerns - themselves were Calvinists. But also more and more Lutherans moved in. Therefore in 1708 the New Church became a Calvinist and Lutheran Simultaneum.
The site for the church was disentangled from the so-called Swiss Cemetery, which had been provided for Huguenots, who had come to Berlin between 1698 and 1699 from their intermittent refuge in Switzerland. The original building had a pentagonal groundplan with semicircular apses. The interior was characterised by a typical Protestant combined altar and pulpit leaning against the eastern central pillar opposite to the entrance.
In 1780 Carl von Gontard designed and started the construction of a tower, easterly adjacent to the actual prayer hall. His design of the domed towers, a second one being added to the French Church, followed the Palladian tradition and received the shape of the Parisian Church of Sainte-Geneviève (now the Panthéon), then still under construction by Jacques-Germain Soufflot. The construction of the domed towers aimed at making the Gendarmenmarkt resemble the Piazza del Popolo in Rome. Still under construction the tower of the New Church collapsed. Thus Georg Christian Unger was commissioned to carry out Gontard's plan.
Christian Bernhard Rode created the statues, representing characters from the Old and New Covenant, which are added to the tower. The dome was topped by a statue symbolising the victorious virtue (now a post-war replica). The gable relief depicts the Conversion of Sha'ul Paul of Tarsus. In 1817 the two congregations of the German Church, like most Prussian Reformed and Lutheran congregations joined the common umbrella organisation named Evangelical Church in Prussia (under this name since 1821), with each congregation maintaining its former denomination or adopting the new united denomination.

On 22 March 1848 the coffins of 183 Berliners, who had been killed during the March Revolution, were shown on the northern side of the church. After an Evangelical service within the prayer hall outside an Evangelical pastor, a Catholic priest and a rabbi, one after the other, shortly addressed the audience, before the throng accompanied the coffins to the graves.
In 1881 the dilapidated prayer hall was torn down and Hermann von der Hude and Julius Hennicke replaced it with a new one on a pentagonal groundplan, according to the neobaroque design of Johann Wilhelm Schwedler. Otto Lessing designed the six statues on the attic of the new prayer hall. On 17 December 1882 the new prayer hall was inaugurated.
In 1943 the New Church was almost completely destroyed in the bombing of Berlin in World War II and was subsequently rebuilt from 1977 to 1988. Meanwhile the German government acquired the building and the site. The church building was updated, deconsecrated and reopened in 1996 as the Bundestag's museum on German parliamentary history.
The two congregations of the New Church maintained cemeteries with the two congregations of the neighbouring Jerusalem's Church (another simultaneum), three of which are comprised - with cemeteries of other congregations - in a compound of six cemeteries altogether, which are among the most important historical cemeteries of Berlin. They are located in Berlin-Kreuzberg south of Hallesches Tor (Berlin U-Bahn) (Friedhöfe vor dem Halleschen Tor).References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
