"The Volksgarten is situated in the 1st district and was designed in 1819. In 1822 Peter von Nobile established a coffeehouse in the Volksgarten which was also the scene of concerts by Johann Strauss the Elder, Josef Lanner and others. Special attractions in the Volksgarten are the Theseus Temple, a basin with fountain sculptures by V. Tilgner, the Grillparzer monument by C. Hasenauer, C. Kundmann and R. Weyr and a marble monument of the enthroned Empress Elisabeth (by H. Bitterlich)."
