Reposaari Fortress (Reposaaren linnakepuisto) was a coastal defence system built in the 1930s. It was designed to protect the important harbor of Pori against Russian fleet. The stronghold area is about 20 hectares and consists of two gun positions, magazines, dugouts, trenches etc. Wooden buildings have been reconstructed in the 1990-2000s.
During the Winter War Reposaari Fortress eliminated one Russian bomber and heckled several bombing operations. Finnish Defence Forces used the fortress until 1964. Today the area is restored and open to the public.
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.
