Bikernieki Memorial is a war memorial to The Holocaust victims of World War II in Bikernieki forest, near Riga. Bikernieki forest is the biggest mass murder site during The Holocaust in Latvia with two memorial territories spanning over 80,000 square metres with 55 marked burial sites with around 20,000 victims still buried in total.
The memorial was initially planned and construction started in 1986, but was delayed after Latvia declared independence in 1991. The construction was revived in 2000 by German War Graves Commission with the help of local Latvian organisations and several German cities. It was financed mostly by German government and organisations, Austrian State Fund, and involved city donations. It was designed by Sergey Rizh and opened on November 30, 2001.
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.
