The Mariinsky Theatre (Russian: Мариинский театр , Mariinskiy Teatr, also spelled Maryinsky or Mariyinsky) is a historic theatre of opera and ballet in Saint Petersburg, Russia.  Opened in 1860, it became the preeminent music theatre of late 19th century Russia, where many of the stage masterpieces of Tchaikovsky, Mussorgsky, and Rimsky-Korsakov received their premieres.  Through most of the Soviet era, it was known as the Kirov Theatre.  Today, the Mariinsky Theatre is home to the Mariinsky Ballet, Mariinsky Opera and Mariinsky Orchestra.

Duderhof Heights or Duderhof Hills (Russian: Дудергофские высоты ; German: "Duderhofer Höhen" ) is a small highland area in the southwestern part of Saint Petersburg (Krasnoselsky District), to the south of the town of Krasnoye Selo, on the northern edge of the Izhora Plateau, which consists of several hills, most notably, the Orekhovaya hill (Russian: Ореховая гора , lit.  "Hazel Hill", ), the highest point of Saint Petersburg at 176 m (577'), in the south, and the Voronya hill (Russian: Воронья гора , lit.  "Crow Hill", ), 147 m (482'), in the north.  Sometimes other smaller hills are considered part of the area as well: the Lysaya hill (Russian: Лысая гора , lit.  "Bald Hill") further northward, the Kirchhof hill (Russian: гора Кирхгоф ) to the east, and the Kavelakhtinskaya ridge (Russian: Кавелахтинская гряда ) further to the south (however, all the smaller hills are situated in Leningrad Oblast rather than in Saint Petersburg).  Since 1992 the Orekhovaya and Voronya hills have been designated as protected natural area (of about 66 ha), divided by Sovetskaya Street of the settlement Mozhaysky into two parts.  Nowadays both hills are mostly covered by broadleaf forests (with "Acer platanoides", "Fraxinus excelsior", "Tilia cordata", "Ulmus glabra", "Quercus robur", "Corylus avellana"), very uncommon for the region situated in the taiga belt, and have a peculiar fauna and flora.  The steep slopes of the hills and alkaline soils on the limestone bedrock are also notable.  For a critically endangered species of weevil, "Otiorhynchus rugosus" Humm., this is the only known location in European Russia.  This is also the only site in Saint Petersburg and Leningrad Oblast where European Beech is able to overwinter in cultivation, albeit suffering considerable dieback.
