The St. Olaf's Church in Tyrvää is a late medieval stone church built probably in 1510-1516. Archeologists have found evidences that the church site has been a spiritual place even in 1000 BC. The settlement has concentrated to the Vanhankirkonnimemi area during the end of Iron Age. There may have been two wooden churches before the present one built in the 14th century. The St. Olaf's Church was probably extended in the 17th century by local family of Nuutila.
When the new wooden church was completed in 1855, St. Olaf's church was abandoded for one hundred years. The church was well known of it's unique interior, until it was burnt down by a pyromaniac in 1997. The church was rebuilt by local people and the interior paintings were created by painters Kuutti Lavonen and Osmo Rauhala.
Finnish National Board of Antiquities has named the church site as national built heritage.
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.
