The Last Berlin Wall Watchtowers: Four Left Standing and Where to Find Each One

The Last Berlin Wall Watchtowers: Four Left Standing and Where to Find Each One

Step off the S-Bahn at Treptower Park, walk south along the Spree for twenty minutes, and you find a concrete cylinder rising from the weeds. That is the Stralau peninsula tower, one of only four surviving GDR border watchtowers from the 302 that once lined the Wall. The other three are scattered across the city from Mitte to the northwestern edge. None are clustered. These four survive because local initiative or monument protection beat the demolition orders that took down the rest by the end of 1992. Each has a different story, a different level of access, and a different reason to visit.

Berlin Wall Watchtowers Still Standing: the Full Count

Four remain. The Federal Property Office ordered the removal of the rest between February 1990 and late 1992 under the border opening protocol. Two are the square BT-6 type with a six-sided observation cabin, flat roof, and steel frame standing about 8 metres high. Two are the round BT-11 type, a three-storey concrete tower with a domed roof and ventilation cap, reaching about 10 metres. The two BT-11 towers sit on the northwestern edge of the city, inside the modern Brandenburg state boundary. The two BT-6 towers are inside the Berlin city limits. That geographic spread is the main challenge: visiting all four in a single day requires three hours of transit time and a reliable BVG ticket validated before boarding.

Potsdamer Platz Watchtower: the Most Accessible

Getting There and Getting In

The tower sits on the southern edge of the redeveloped district at Kieler Straße 2, Mitte. Take the U2, S1, S2, or S25 to Potsdamer Platz station. This is the most visible of the four, but it is now dwarfed by the corporate towers built on top of what was Europe's largest construction pit in the 1990s. The tower type is a BT-6. It was saved by the citizens' association Bürgerverein Kieler Eck e.V. and now operates as the Gedenkort Kieler Eck. Public access is limited: the interior is open April through October on Sundays from 14:00 to 16:00. These hours are set annually and may change. Check the association's posted schedule before you go. Outside those hours you can see the tower from the street, but the fence stays locked.

What Stands Around It Now

The death strip that once ran beside this tower is now the business and retail zone of Potsdamer Platz. The Info Box, the red container on stilts where visitors watched the new city rise, is gone. You are standing on a traffic island that was a border strip. The contrast is the point.

Erna-Berger-Strasse Watchtower: the Hidden One

A short walk from the Kieler Straße tower, the second BT-6 sits behind a construction site fence on Erna-Berger-Strasse, near the intersection with Potsdamer Strasse. Use Potsdamer Platz station again. This tower is harder to photograph and easier to miss entirely. It is not a dedicated memorial. It is a listed building protected by the Land Berlin, but the construction hoardings around it mean you can only see the upper cabin from specific angles. The interior is not open to the public. If you are walking the double cobblestone line that marks the Wall's path, you will pass within metres of it without realising. Use a dedicated map app rather than Google Maps, which sometimes misplaces the marker.

Kieler Strasse Watchtower: the Listed Monument on a Traffic Island

The name is confusing: the Kieler Straße 2 address belongs to the tower at Potsdamer Platz. The structure sits on a grass traffic island at the junction of Kieler Strasse and Pohlstrasse. The designation as a listed monument means it cannot be altered, demolished, or obscured by new construction. The public access is the same: exterior visible at all times, interior open Sundays 14:00 to 16:00 during the warm months. The traffic island setting means you cannot stand directly beneath it without crossing a road. Arrive by U2 or S-Bahn to Potsdamer Platz and walk ten minutes northwest.

Stralau Peninsula Watchtower: the Remote One in Treptow

Finding It

The fourth remaining tower is the hardest to reach. Its official name is Schlesischer Busch, and it sits on the Stralau peninsula at Puschkinallee, Treptow. The tower is a BT-6 type, listed as a protected monument by the Land Berlin in 1992. Take the S8, S85, or S9 to Treptower Park station. From the station, walk south along the Spree river path for about 20 minutes. The tower is not visible from the station. The path follows the Mauerweg, the Wall trail, and passes a section of the death strip that has been left as open grass. The tower itself is gated. The exterior is always accessible; the interior is open only by guided tour, with dates published by the Bezirksamt Treptow-Köpenick. Check their site before you make the walk. It is a long one to arrive at a locked gate.

What Stands Around It Now

The Stralau peninsula was a wasteland during the Cold War, a narrow strip of land between the Spree and the East Berlin border fortifications. Today it is a mix of new apartment blocks, a small beach bar, and the gravel paths of the Mauerweg. The tower is the only border structure left. Continue south along the river and you reach the Insel der Jugend, a club site that was a GDR youth centre.

GDR Border Tower Locations Berlin: the Two Outside the City

Nieder Neuendorf

The BT-11 round towers at Nieder Neuendorf and Hohen Neuendorf sit on the northwestern and northern edges of the city. Each is a Gedenkstätte, a memorial site with exhibition space inside. Nieder Neuendorf is at Hennigsdorfer Straße, Hennigsdorf. BT-11 type. Restored in 1998. Open March to October Tuesday through Sunday 10:00 to 17:00, and November through February Tuesday through Sunday 10:00 to 16:00.

Hohen Neuendorf

Hohen Neuendorf is at Schönfließer Straße. BT-11 type. Listed monument since 1999. Exterior always visible; interior open the first Sunday of each month 14:00 to 17:00. Both require a regional train or a car to reach. If you have only one morning, skip these and focus on the two BT-6 towers in Mitte and Treptow.
