Bråborg was a former Royal castle at Bråviken. The house was built by Queen Dowager Gunilla Bielke in 1588-1590 and she lived there after her husband, King John III of Sweden, died in 1592. Gunilla Bielke herself died at Bråborg in 1597. Bråborg was later owned by her son, duke John of Östergötland. In 1612 he married his cousin, princess Maria Elisabeth of Sweden. They both died at Bråborg in 1618.
The building was partly destroyed in a fire in 1669, and in 1719 it was burnt down by a Russian army. The army also attacked the nearby town of Norrköping. The inhabitants needed stone to rebuild their town and used building material from the ruins of Bråborg. The new manor house at Bråborg was built about 1,000 metres from the burnt down house.
Today, a ruin is all that remains of the estate. The foundations and cellars are still visible today, together with the moats and parts of the gardens.
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.
