Saint Sophia Greek Orthodox Cathedral was founded as a church in 1904 to serve the Greek Orthodox residents of the District of Columbia. In 1962, the church was elevated to a cathedral. The building is in the Neo-Byzantine style with a central dome that reaches 24m in height.
The congregation met in temporary quarters for several years, prior to the construction of its own church near 8th and L Streets NW which was dedicated in 1924. This site is currently occupied by the Walter E. Washington Convention Center. Construction on the current edifice at 2815 36th Street NW, near Massachusetts Avenue and a short distance from the Washington National Cathedral, began in 1951. The congregation began worshipping there in 1955 shortly after major construction was completed. Although the building has been in use for over fifty years, the interior decoration is incomplete. Work began on the interior in 1965 and continues to the present.
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.
