Brynolf Algotsson, Bishop of Skara, laid the foundations for a fortified castle in Läckö in 1298 originally as a fort that consisted of two or three houses surrounded by a wall. After a fire during the 1470s, the fort was expanded by bishop Brynolf Gerlachsson.
After the reformation in 1527, King Gustav Vasa took possession. Field Marshal Jacob Pontusson De la Gardie was granted the property in 1615. Field Marshal de la Gardie embarked on an extensive building spree, including the third floor of the keep. The portal to the main courtyard was added during his period, as were the frescos depicting people and winding plants found in niches, stairwells and the rooms on the third floor. In 1654, Count Magnus Gabriel De la Gardie initiated immense construction projects at Läckö. A fourth floor was built in the main building and a number of artists were hired to decorate the walls and ceilings of the castle.
Läckö Castle is a national monument and has been managed by the National Property Board since 1993.
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.
