"Sans souci," which means without care, is what Prussian King Fredrick the Great wished to be when he had his summer residence built in 1747. It was intended to be a small affair, only 12 rooms, located on a vineyard. But the place is anything but tranquil these days — Frederick's favorite palace has become the main tourist attraction in Potsdam.

Frederick the Great ignited a building boom in Potsdam that resulted in 17 palaces and castles. Most are surrounded by wonderful parks and gardens, many of which have been awarded World Heritage status by UNESCO.

Modern art in a baroque palace: The Museum Barberini, located in Barberini Palace, features artworks from East Germany, post-1989 German art, as well as major impressionist works. The palace that houses the museum was modeled after the Palazzo Barberini in Rome — the original Potsdam building was heavily damaged during World War II.

Potsdam is located on a peninsula and surrounded by seven lakes. The best way to explore these is by boat. Many tourist attractions can be visited by water taxi, including the futuristic Hans-Otto-Theater building.

Badly damaged during the Second World War, the building's ruins were demolished by the former East German government. From 2010 to 2014 it was reconstructed, complete with historical facades and a modern interior. Today, the building houses the Brandenburg state parliament.

Although at first glance it may appear to be one of Potsdam's many palaces, this impressive domed building is St. Nicolas Church. It was constructed between 1830 and 1850 based on plans by Karl Friedrich Schinkel, the Prussian star architect of the neoclassical era. Reaching a height of 77 meters, the domed-church distinctly defines Potsdam's city center.

During the 18th-century building boom, there was a lack of skilled workers. Some 134 houses were built in the Dutch style in order to tempt builders from Holland to move to Potsdam. Although the plan failed to attract the labor force, it did create a charming quarter with small cafés and shops that are popular with tourists.

The idyllic country house residence was originally built for the Prussian crown prince. In 1945, it came into the world's focus as the location where Josef Stalin, Winston Churchill and Harry Truman held the Potsdam Conference. Here, the leaders of the Soviet Union, Great Britain and the USA made important decisions that affected post-war Europe. The Cold War began shortly thereafter.

One shore in Berlin, the other in Potsdam — the Glienicker Bridge is a straightforward connection between the two cities. However, from 1961 until 1989 the Berlin Wall ran right across the center of the bridge, making it an ideal point of exchange for captured secret agents of both political systems. Steven Spielberg even used it as the setting for his 2015 film "Bridge of Spies."

Many big names have stood in front and behind the camera in Potsdam, including Tom Cruise, George Clooney, Tom Hanks and Brad Pitt to name a few. The Babelsberg film studios were founded in 1912 and are among the most prominent studios in Europe. The set "Berlin Road" (pictured) cost €16 million ($18.8 million) to build and is intended to attract big productions to Potsdam.

The houses were constructed by a Prussian architect under Peter Joseph Lenné, the director general of the Royal Prussian palaces, in the style of traditional German timbered houses. Only the cladding was done in Russian style in an attempt to imitate a so-called "Izba", a traditional Russian wooden house.

A total of 14 such houses, a church and a church house were built in 1826-27. In line with a meticulously organized plan, the homesteads were erected on two cross streets. Streets in real Russian villages never looked so orderly. But in the Prussian context, the order was quite appealing. Each grange was given a plot of land where people could plant fruit trees and vegetables.

The biggest house at the crossing of the two streets was reserved for the village elder. Prussian King Frederick William III, who had a keen interest in Russian art and architecture, ordered designs with ornaments and motives of Russian wooden architecture from Saint Petersburg (later Leningrad), to make sure the buildings would be constructed in the proper style.

Nowadays, the building houses a small private museum. It was initiated by Hermann Krämer, a doctor from Westphalia, who was a big fan of Alexandrovka. The small exhibition attempts to reconstruct the way of life of the first colonists.

What would be a village without a church? This church in Alexandrovka was inaugurated in 1829 and devoted to St. Alexander Yaroslavich Nevsky, who served as Prince of Novgorod in medieval times. Interestingly, he was beatified by the Catholic Church after having defeated the Teutonic Order in 1242.

Most of these homes have come into private ownership after German reunification. They are seen as very special buildings in a booming region with mostly modern homes. Alexandrovka is part of Potsdam's celebrated cultural region that has been declared a UNESCO World Heritage Site.

The fruit garden that was created with the construction of the colony was owned by the Prussian king. However, the colonists were allowed to keep a part of the harvest for themselves, or to sell it.

Alexander Jablokov (honored in the pictured plaque) was one of the twelve singer soldiers that inspired Alexandrovka. His son Nicolaj also lived in the village. The last Russian singer soldier died in 1861. During the Weimar Republic, only four families with Russian roots still lived in Alexandrovka. The last descendant of the Russian colonists died in 2008.

And yet, Alexandrovka has remained an appealing monument that documents a part of history that was shared by Prussia and Russia. It's a connection that is not limited to architecture, but has remained in the collective memory of both Germans and Russians.
