Stralauer Allee
Now retrace your path back to the beginning of the peninsula. But, instead of turning back onto Kynaststraße, stay on Alt Stralau and cross the train tracks, where the road becomes Stralauer Allee. On both sides of the Spree you can see sites of the Mediaspree Project.
The Mediaspree Project is one of the most ambitious urban development projects in Europe. Along 3.7 km on both banks of the Spree, a new neighbourhood is rising, with architecturally outstanding new buildings and lavishly renovated old buildings, such as the MTV and Universal buildings.
Oberbaumbrücke
To your left, you will see the Oberbaumbrücke. While Germany was divided, the bridge was a border crossing for pedestrians. Since the fall of the Berlin Wall, it now connects the two halves of the district of Friedrichshain-Kreuzberg.
East-Side-Gallery
Cross Warschauer Straße and continue riding along the river on Mühlenstraße. On the left-hand side, you will see the 1316 metre long East Side Gallery, the longest open-air gallery in the world with over 100 images painted onto the former Berlin Wall.
After a few metres, you'll pass the O2 World arena on your right. O2 World is an impressive event venue, where sporting events, concerts and other events are held.
Stay on Mühlenstraße several blocks past the O2 and then turn right onto Straße der Pariser Kommune. Ride down this street until you come to Ostbahnhof.
Ostbahnhof
Ostbahnhof serves various S-Bahn, long-distance and regional rail lines. A large flea market is also held here on Sundays.
Stay on Straße der Pariser Kommune past Ostbahnhof, riding through Franz-Mehring-Platz and then on to Karl-Marx-Allee, which you’ll reach in a few minutes. As you ride, you'll see a lot of prefabricated buildings from the GDR period to your left and right.
Karl-Marx-Allee
Karl-Marx-Allee is impressively wide in some spots. The road itself, though, is surprisingly small, while the tree-lined pavements are very wide. A striking feature here are the unique residential and commercial tower houses in the so-called "Socialist Classicist" style, also called "Stalinist Baroque".
Turn left onto Karl-Marx-Allee and follow it until you come to Straußberger Platz, a large roundabout. Turn right at the roundabout onto Lichtenberger Straße, which leads to Platz der Vereinten Nationen. Across the way is the Volkspark Friedrichshain, a wonderful place to take a detour.
Volkspark Friedrichshain
The Volkspark Friedrichshain is a 49 hectare municipal park, which was established in 1846. The park features numerous tourist attractions including the Märchenbrunnen (Fairy Tale Fountain), the small and large bunker hill (Mont KIamott), the Weltfriedensglocke (World Peace Bell), the Freiluftkino Friedrichshain (Friedrichshain open-air cinema), the Denkmal der Spanienkämpfer (monument to the Spanish Civil War), and much more.
Frankfurter Tor
Hang a right onto Landsberger Allee on the right side of the Platz der Vereinten Nationen and then continue for several blocks. Take a right into Petersburger Straße and ride across Besarinplatz until you come to the Frankfurter Tor (the Frankfurt Gate). Here you can see the striking towers at the corners.
Cross over Karl-Marx-Allee onto Warschauer Straße. Stay on Warschauer Straße until you can turn left into Boxhagener Straße. Continue to no. 17, the end of the tour.
