Park Tower, formerly known as SGZ-Hochhaus, is a high-rise building in the Westend-Süd district of Frankfurt, Germany.

[2] The then 96-metre-high (315 ft) building with a black-and-silver facade was briefly the tallest skyscraper in Frankfurt.

It is located in Reuterweg near the Opernplatz and stands slightly oblique to the old opera house.

Following plans by the architects Albert Speer & Partner, it was increased by three levels and supplemented with a second block which lies down like a stone belt around the shaft of the tower.

The now 115-metre-high (377 ft) building offers approximately 24,000 square metres of gross floor area.
