On the historic grounds of Germany’s first airfield at Johannisthal stands an aeronautical experimental park that traces key steps in aviation research. The site brings together several standalone technical monuments, each built for a specific purpose and time in the evolution of flight testing.
The Großer Windkanal, a high-speed wind tunnel constructed between 1932 and 1934, was built to be walked through, allowing close inspection of its interior. Nearby stands the Trudelturm, a vertical wind tunnel from 1934 to 1936 designed for spinning tests. Here, aerodynamic behavior in dangerous spin conditions could be studied and understood with greater precision.
The Schallgedämpfter Motorenprüfstand, created from 1933 to 1935, served as a sound-insulated test bed for aircraft engines. Its design helped reduce noise while allowing engineers to measure performance and stress under controlled conditions.
Set about 500 meters from the other structures are the Isothermische Kugellabore, also known as the Adlershofer Busen. Built between 1959 and 1961, these spherical laboratories were dedicated to experiments requiring stable temperatures, supporting research that demanded precise environmental control.

Jewish cemetery and lapidarium with old tombstones.
Berlin's biggest lake and popular resort for bathing and watersports. You can also travel there by tram, which is an experience by itself.
A remarkable medium-sized classical castle by the famous K.F. Schinkel built 1820 to 1824, also called "Humboldtschlösschen", because Alexander and Wilhelm von Humboldt (and their family) lived here once. Still privately owned.
One of the most authentic and oldest villages (1247) in the outskirts of Berlin, it looks the same way it did some hundred years ago. Take S-Bahn 1 to Waidmannslust and then bus 222 to Alt-Lübars.
The city's Protestant cathedral and the burial place of the Prussian kings. You can climb to the top and get a view of the city.
This heritage-protected public bathing beach which opened in 1907 is one of the largest inland lidos in Europe and has a 1275-m-long sand beach, a capacity for up to 30,000 guests and a popular nudist area.
The memorial site stretches along the full 1.5-km length of Bernauer Straße. The listing marker points to the visitor centre. Various monuments can be found along the entire length of the street, documenting nearby escape attempts and tunnels; captions are in German and English. The documentation centre across the street on Bernauer Straße/Ackerstraße is excellent (although most of the documentation is in German). The viewing platform next to the documentation centre gives you a tiny hint of the true scale of the Wall and how terrifying the "no man's land" between the two sections of walls must have been. The monument (that you can see from the platform) is a complete section of 4th generation wall - both inside and outside sections, and you can peer through from the east side to see the remains of the electric fence and anti-tank devices in the death strip. It really helps you understand what an incredible feat it was to get from one side to the other -- and why so many died doing it. The memorial site is often missed by tourists but an absolute must for anyone interested in this part of the city's history. It's a memorial to those who died crossing, so you won't, fortunately, get the tackiness of the Checkpoint Charlie area; instead you will be left with a haunting feeling of what life with the wall may have been really like.Bernauer Straße is a street with a great deal of Wall history: it came to tragic prominence on August 13, 1961 when East German authorities closed the border and the street (with houses in the East but the street in the West). Border guards walled the doors and windows shut to keep Easterners from escaping by jumping out the window while Westerners (including police and fire brigades who brought life nets to help catch refugees) looked on in horror. The first recorded Wall-related death - the notorious Peter Fechter case (he bled to death in the "no-man's-land" with both sides unwilling or unable to help him) - was here, as was one of the famous tunnels and the famous photograph of the GDR border guard leaping over the barbed wire.
A beautiful landscape of water canals and vegetation with charming little fish restaurants.
Designed by Daniel Libeskind with an excellent exposition on the Jewish life in Berlin and the impact of the Holocaust. You can easily spend a day here. There is a metal scanner and other security features you'd rather expect at an airport than a museum.
Gothic church, the second oldest (built in late 13th century) of the historical centre of Berlin. It's the highest church tower of Berlin (about 90 m), but seems rather small beneath the gigantic TV tower. The church tower was built in the late 18th century by Carl Gotthard Langhans, the architect of the Brandenburg Gate.
A fortress built between 1560 and 1590 to Italian design on the site of a 12th-century castle. The Juliusturm housed part of the huge indemnity (in physical gold coins) France had to pay after the war of 1870/71 until what was left of it was returned to France after Germany's loss in World War I. The term "Juliusturm" remained in usage in German for a large "rainy day fund" into the 1960s. Museums housed within the citadel cover the history of the town of Spandau, monumental public art in Berlin, and artillery.
