Reinickendorf and Spandau

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. There is also a gallery of contemporary art, displaying temporary exhibitions.

A splendid 15th-century Gothic church with many fine accoutrements.

At a former Luftwaffe and Royal Air Force (RAF) airfield, RAF Gatow. The museum's focus is on military history, particularly the history of the Luftwaffe of the Bundeswehr, with a collection of more than 200,000 items, including 155 aeroplanes, 5,000 uniforms and 30,000 books. There are also displays (including aeroplanes) on the history of the airfield when it was used by the RAF. Aircraft include reproductions of Otto Lilienthal's gliders, of World War I planes such as the Fokker E.III, and World War II planes such as the Bf 109 and Me-262, as well as at least one aircraft of every type ever to serve in the air forces of East and West Germany. Most of those postwar aircraft are stored outside on the tarmac and runways, however, and many are in bad condition. There are long term restoration projects, including a Focke-Wulf Fw 190. RAF Gatow is notable as the "missing third airport" of West Berlin. Each sector used to have its own airport; the French sector had Tegel, the American sector had Tempelhof and the British had Gatow. However, RAF Gatow never saw much traffic of any kind, was more kept as a political statement than for transportation value, and thus was shut down after reunification. Tempelhof, after having been shut down for civilian traffic from 1975 to 1981, closed for all flights in 2008, while Tegel shut down in November 2020.

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.

Not far away from Schloss Tegel (at the "große Malche") you can take a look at the oldest tree in Berlin, an oak which has been growing there since about 1192 (so it's actually older than Berlin itself). The name ("fat Mary") allegedly stems from the brother Humboldt who named the tree after their overweight cook.

During the International Building Exhibition 1984 to 1988 a bunch of remarkable buildings were set around the old Tegeler Hafen. Architecturally diverse, the most important is the Phosphateliminierungsanlage (Gustav Peichl). Also some buildings by Charles Moore are interesting.

Ex-industrial buildings from the late 19th and early 20th century, nice clinker-architecture and the first (mini) highraiser of Berlin, the Borsigturm, 65 m high, built 1922-24. The area houses now offices, a shopping mall and some places for entertainment. The company Borsig has a very turbulent and storied history and while it has long since ceased being a "German" company or connected to the family of the same name, the investors that bought the name and assets after a bankruptcy keep producing in Berlin-Tegel.

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.
