The Württemberg Mausoleum is a memorial standing on the peak of Württemberg Hill at the westernmost end of Schurwald woods overlooking the Neckar river. The memorial was built for Catherine Pavlovna of Russia (1788–1819), the second wife of William I of Württemberg (1781–1864). The remains of William I and his daughter Maria Friederike Charlotte of Württemberg (1816–1887) are also housed in the mausoleum.
The mausoleum was built after the death of Queen Catherine between 1820 and 1824 based on a design drafted by Giovanni Salucci. The location on the former site of Wirtemberg castle was chosen as the home of the House of Württemberg.
Between 1825 and 1899 the mausoleum was used as a Russian Orthodox Church place of worship. The memorial is still used to this day for a Russian Orthodox service every Pentecost.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
