The Protestant Church of the Redeemer (Heilandskirche) is famous for its Italian Romanesque Revival architecture with a separate campanile (bell tower) and for its scenic location. It was built in 1844. The design was based on drawings by King Frederick William IV of Prussia, called the Romantic on the Throne. The building was realized by Ludwig Persius, the king's favorite architect. The church is situated on the bank of lake Jungfernsee, 300 metres south of Sacrow Manor at the edge of its park, designed and expanded in the 1840s by landscape architect Peter Joseph Lenné. Both church and manor were restored in the 1990s. This area of lakes, forests, parks, and castles has been classified as a World Heritage Site by UNESCO.
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.
