The first evidence of Pyhtää as an independent parish dates back to 1380. At that time already the parish had a church, but it is not known where it was situated or what it looked like. Until 1600 Pyhtää included, besides its present area, also half of the present city of Kotka, Ruotsinpyhtää, Elimäki, the western parts of Anjalankoski, and a part of Lapinjärvi.
Dedicated to St. Henry, the church is situated where one of the westernmost branches of the river Kymi meets the ancient Turku-Viipuri coast road.
The building resembles the majority of the Finnish medieval stone churches. Pyhtää church, built about 1460, has retained its original medieval appearance almost untouched. There have been few alterations: the porch was converted into a memorial choir during the latter half of the 18th century, and in connection with repairs in 1907, buttresses were built to support the north wall and the sacristy was fitted with the outer entrance.
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.
