The first trip hammer in Forsbacka was mentioned in 1591. In 1640 Dutchman Henry Marhein built an ironworks. The 18th century was the golden age of Forsbacka. The first blast furnace was built in 1744. Several workshop buildings were built in next decades, as well as a luxurious Forsbacka Manor in 1777. It contained a stable, English-style park and Orangery.
Today Forsbacka is an old ironworks environment that has been restored and open to the public. During the summer a variety of exciting art exhibitions are hosted in the old ironworks buildings, together with exhibitions on the industrial history of the area. You can see products manufactured here, and tools and equipment used. There is an idyllically situated little cafe here in the lovely grounds.
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.
