Reunified Berlin's ubiquitous examples of architectural citation—such as the Reichstag, the plans for the Stadtschloß, the Sony Center at Potsdamer Platz, the new Hotel Adlon, and the FriedrichstadtPassagen—variously inscribe contemporary architectural styles with allusive reinventions of previous forms and cultural discourses, incorporate remnants of older edifices, or use partial reconstructions for new social purposes. In the process, these projects problematize conventional principles of architectural restoration by dramatizing a productive tension between past and present, between authenticity and simulation, between genuine nostalgia and the sometimes cynical manipulation of historical memory. Relying on the synchronicity of (seemingly) nonsynchronous styles, architectural citation goes beyond postmodern pastiche; such citation signifies Berlin's renegotiation of its identity as the new-old capital by recycling half-obliterated and yet irrepressible traces of urban history within the parameters of international capitalism, Europe-directed national politics, and the rampant tourist industry.
