Adornodenkmal, Glass cube memorial at Westend Campus, Frankfurt, Germany.

The Adornodenkmal is a transparent glass cube on the Westend Campus of Goethe University Frankfurt. Inside it, a desk, a chair, and several objects recreate the workspace of philosopher and music theorist Theodor W. Adorno.

The memorial was inaugurated on 10 October 2003, the 100th anniversary of Theodor W. Adorno's birth, on the square in Bockenheim that had been named after him in 1995. It replaced the Husarendenkmal, which was moved to the Senckenberganlage. In April 2016 the installation was relocated to the Theodor-W.-Adorno-Platz on the Westend Campus of Goethe University.

Quotes from Adorno's writings are engraved on marble slabs placed around the glass cube, inviting visitors to read his words up close. The texts come from different works and give a direct sense of how he thought and wrote.

The cube is sealed and neither heated nor ventilated; its lamp and metronome are controlled from a maintenance tunnel reached through a round manhole cover a few metres outside the installation. The inner floor hatch, hidden under a square panel beneath the desk, is not for visitors. Since the move to Campus Westend the memorial has stood on Theodor-W.-Adorno-Platz.

Inside the cube, a metronome ticks at an angle on top of a book, a detail that points to Adorno's deep engagement with music theory. It is easy to miss at first glance, but it quietly says a great deal about how central music was to his work.
