Prinzessinnenpalais/ Princess Palace, Berlin

The Prinzessinnenpalais (Princesses' Palace), also known today as the PalaisPopulaire, is a historic royal residence at Unter den Linden 5 in Berlin-Mitte, forming part of the Forum Fridericianum ensemble. It stands in a prime location on the grand boulevard, adjacent to the Kronprinzenpalais (to which it is linked by an arched bridge) and near the Staatsoper Unter den Linden. Originally built as a private residence for Prussian royalty—specifically housing the daughters of King Frederick William III and Queen Louise—it exemplifies the layered architectural evolution of 18th- and early 19th-century Berlin, blending Prussian Rococo with Neoclassical restraint. Today, its faithfully reconstructed historic exterior contrasts sharply with a minimalist, exposed-concrete modernist interior, reflecting Berlin's turbulent 20th-century history.

 

History

Origins and 18th-Century Construction (1730–1788)
The building’s roots trace to 1730, when two separate residential houses were erected along Oberwallstraße, beside the former Berliner Festungsgraben (fortress moat). One belonged to General von Becheffer (or a similar high official), the other to Prussian Finance Minister Samuel von Cocceji (later a key legal reformer under Frederick the Great). These were functional, unpretentious structures reflecting the pragmatic urban development under King Frederick William I (“the Soldier King”).
In 1733, architect Friedrich Wilhelm Dieterichs (sometimes spelled Diterichs) unified the two houses into a single elongated palace by inserting a central projecting section (Mittelrisalit). The design followed the Friderizian Rococo style—elegant yet restrained Prussian Baroque with symmetrical facades, pilasters, curved elements, and decorative stucco. The palace oriented perpendicular to Unter den Linden, with Cocceji residing there until his death. It initially served administrative and minor noble purposes rather than grand royal display.
Ownership changed in 1755 to Margrave Friedrich Heinrich von Brandenburg-Schwedt (a Hohenzollern relative, sometimes called the “wicked Margrave”). After his death in 1788, the property transferred fully to the Prussian royal house (Hohenzollerns). This marked its shift from private/official use toward courtly residence.

19th-Century Royal Residence and Neoclassical Expansion (1809–1918)
Under King Friedrich Wilhelm III, the palace became intimately tied to the royal family. In the early 19th century, it housed Crown Prince Friedrich Ludwig Karl (a son of Frederick William II) briefly before serving as home to the king’s three daughters: Princess Charlotte (1798–1860, later Empress consort of Russia as wife of Nicholas I), Princess Alexandrine (1803–1892, later Grand Duchess of Mecklenburg-Schwerin), and Princess Luise (1808–1870, later Princess of the Netherlands). The sisters lived there together, hosting intimate salons, pursuing arts, music, and charity—earning the building its enduring name, Prinzessinnenpalais (“Princesses’ Palace”).
A famous visual record is Franz Krüger’s painting Parade auf dem Opernplatz (1824–1830), which depicts the princesses and court society observing a military parade from the palace windows while the king and Czar Nicholas I review troops on Unter den Linden.
Architecturally, major upgrades occurred 1810–1811. Queen Luise initially commissioned Karl Friedrich Schinkel for a grand head building (Kopfbau) facing Unter den Linden, but costs led to Heinrich Gentz executing a more restrained Neoclassical extension instead. Gentz added the prominent front section with large rectangular windows across three floors, symmetrical stone facade, and classical restraint. Schinkel still contributed a connecting Schwibbogen (arched bridge) to the neighboring Kronprinzenpalais, physically and symbolically linking the two royal residences. After Queen Luise’s death (1810), the morganatic wife of Friedrich Wilhelm III—Countess Auguste von Harrach (Fürstin Liegnitz)—resided here from 1824 onward. Later, it accommodated other extended family members.
The palace remained a private Hohenzollern residence until the monarchy’s collapse in 1918.

20th Century: Museums, War, and GDR Rebirth (1918–1989)
After 1918, ownership passed to the Free State of Prussia and then the State Museums of Berlin. From 1931 to 1933 (on the 150th anniversary of Schinkel’s birth), it housed the Schinkel-Museum, displaying the architect’s paintings, drawings, and sketches. During the Third Reich, it continued as a museum.
World War II brought near-total destruction. Allied bombing raids (especially 1943–1945) gutted the interior; only outer walls and some facade elements survived. In East Berlin under Soviet/GDR control, the ruins stood abandoned for years while planners documented surviving details with plaster casts (1952–1953 and 1960–1962).
Reconstruction began in 1962 under GDR architect Richard Paulick (Bauhaus-trained). Completed 1963–1964 as part of restoring the Forum Fridericianum, the project recreated the historic Rococo/Neoclassical exterior facade while installing a fully modernist interior with precast concrete. It opened on December 25, 1963, as the Operncafé (Opera Café), incorporating an opera bar, wine tavern, grill restaurant, and terrace overlooking the Operngarten (now part of Bebelplatz). A wrought-iron Rococo railing from the demolished Schloss Buch was salvaged for the staircase. The café became a popular East Berlin social hub, hosting weekly discos (including for the GDR’s gay scene) and serving as a filming location for the 1973 DEFA film Die Legende von Paul und Paula.

Post-Reunification and Contemporary Era (1990–Present)
After German reunification, the building passed to the Treuhand agency. In 1990/1991 it reopened as the Opernpalais with historicizing Rococo-style interiors replacing Paulick’s modernism. Under operator Manfred Otte (until 2011), it gained fame for Europe’s largest selection of cakes and tarts (over 50 varieties), attracting celebrities like Plácido Domingo, Daniel Barenboim, Helmut Kohl, and Richard von Weizsäcker.
In 2012, structural work addressed the postwar concrete framework. From 2017–2018, Deutsche Bank leased the northern section and commissioned Berlin architects Kuehn Malvezzi for a minimalist redesign: exposed concrete core, plain gray floors, white walls, bare ceilings, and 750–900 m² of flexible exhibition space. The entrance shifted to Oberwallstraße. It reopened in 2018 as the PalaisPopulaire, Deutsche Bank’s public art forum showcasing contemporary art from the bank’s collection, international exhibitions, and cultural programs. The ground floor includes the Café LePopulaire. The former Prinzessinnengarten now forms the eastern part of Bebelplatz.

 

Architecture

Construction History and Architects
The palace originated from two separate residential buildings erected in 1730 on Oberwallstraße (along the former Berlin fortress moat) for General von Becheffer and Finance Minister Samuel von Cocceji. In 1733, court architect Friedrich Wilhelm Diterichs (also spelled Dieterichs) unified them into a single cohesive structure by inserting a central projection (Mittelrisalit). This created a narrow, elongated palace oriented perpendicular to Unter den Linden, in the elegant Friderizianisches Rokoko (Prussian Rococo) style—characterized by fluid curves, ornate stucco, and French-inspired symmetry adapted to Prussian tastes.
A major extension occurred in 1810–1811 under King Frederick William III, who commissioned court architect Heinrich Gentz to add a representative Kopfbau (head building or pavilion) projecting forward to align with the Unter den Linden street frontage, between the opera house and the neighboring Kronprinzenpalais. This addition shifted the building's primary orientation toward the boulevard and introduced Neoclassical elements (restrained proportions, classical cornices, and balanced facades). Karl Friedrich Schinkel contributed the elegant Schwibbogen—an arched connecting bridge or gangway linking the two palaces—and may have influenced the front-building design (an earlier 1809 Schinkel proposal was scaled back for cost reasons). The palace served as the residence for the Prussian princesses until the monarchy's end in 1918.
Later ownership passed through the Hohenzollerns (acquired by Margrave Friedrich Heinrich von Brandenburg-Schwedt in 1755), and it briefly housed the Schinkel Museum in the 1930s before wartime destruction.

Exterior Architecture: Layout, Facades, and Stylistic Features
The palace's footprint is narrow and elongated, originally running perpendicular (transverse) to Unter den Linden before the 1811 extension reoriented its main presence toward the boulevard. This creates a distinctive urban form: a long rear wing along Oberwallstraße merging into a more prominent head building on the Linden front.

Oberwallstraße Facade (1733 Rococo Core): This side retains the strongest original character. Diterichs unified the two houses with a symmetrical design featuring a central risalit (projecting pavilion) accented by four Ionic pilasters, an attic storey (Attika), a balcony, and a prominent staircase protrusion (Treppenvorbau). The roof is a classic mansard (curved or broken) form typical of the era. Ornate details include a Wappenkartusche (coat-of-arms cartouche) of the House of Brandenburg-Schwedt on the attic. Light-colored stone and stucco create a refined, elegant Prussian Baroque-Rococo effect with pilasters emphasizing verticality and symmetry.
Unter den Linden Facade (1810–1811 Neoclassical Head Building): Gentz's addition presents a more restrained, classical street front integrated into the Forum Fridericianum's orderly boulevard architecture. It features large rectangular windows across multiple storeys, rusticated bases, prominent cornices, balustrades, and simplified pediments or entablatures. The overall effect is harmonious and symmetrical, using light stone to blend seamlessly with neighboring buildings while projecting royal dignity. Dormer windows punctuate the roofline in the reconstructed form.

The building's materials are primarily light-colored stone and stucco, with wrought-iron elements (including a preserved 18th-century Rococo railing from the demolished Schloss Buch, also designed by Diterichs, now in the staircase). A Baroque garden once bordered the moat but was reshaped over time and now forms a simplified public green space on Bebelplatz.

Interior Architecture: Original vs. Modern
Original interiors (18th–19th century) featured typical Rococo salons and state apartments with ornate stucco ceilings and walls, enfilade layouts for formal processions, and decorative paintings (some documented in historical archives). These suited its role as a princesses' residence but were largely lost to wartime damage.
Post-WWII, the palace was bombed (only outer walls survived) and fully demolished in 1960–1962 due to weathering. Architect Richard Paulick (a Bauhaus-trained GDR designer) rebuilt it in 1962–1964 as the Operncafé, faithfully restoring the historic facades using pre-war measurements and gypsum molds while inserting a modernist concrete core with open, functional spaces.
The current interior (redesigned 2014–2018 by Berlin firm Kuehn Malvezzi for Deutsche Bank's PalaisPopulaire arts center) deliberately exposes Paulick's precast concrete structure for a stark, contemporary contrast: polished gray floors, white walls, exposed beams and ceilings, and minimalist exhibition spaces (about 900 m²). This "anti-interior design" approach highlights the building's layered history without historicist pastiche. A preserved Rococo wrought-iron balustrade in the staircase provides a rare original accent. Ground-floor areas include a café with modern fittings.

Significance and Current State
The Prinzessinnenpalais embodies Berlin's architectural palimpsest: Prussian royal elegance, wartime destruction, GDR modernist reconstruction, and post-reunification cultural repurposing. Its protected status as a Baudenkmal preserves the facades in their 1733/1811 configuration, while the interior's raw concrete serves as a canvas for contemporary art, concerts, and events. This juxtaposition—Baroque/Rococo-Neoclassical shell over a 1960s concrete skeleton—makes it a subtle yet powerful commentary on Berlin's resilience and evolving identity.
