The Protestant parish church at Altenkirchen is one of the oldest church buildings on the island of Rügen. The predecessor of the current church could have been a Slavic burial mound. Soon after the Christianization Danish builders erected a three-nave Romanesque church in 1168. The apse and choir were completed in 1200 and the baptismal font in 1240. There is also a triumphal cross from the 14th century. The freestanding belfry of the church dates from the 17th century. The Baroque altar from 1724 was made in the workshop of Elias Kessler from Stralsund.

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.
