The first Edsberg building was constructed of wood around 1630 as an estate for Henrik Olofsson. It was very soon after completion signed over to count Gabriel Bengtsson Oxenstierna who changed it into a manor in 1647. Queen Christina of Sweden visited and stayed in the house in 1645. In 1670, when the manor had been inherited by the son Gabriel Gabrielsson Oxenstierna, King Charles XI of Sweden and the Queen Dowager Hedvig Eleonora of Holstein-Gottorp came for a visit.
The manor later belonged to the Rudbeck family, the first of which was the Over-Governor of Stockholm, Thure Gustaf Rudbeck. In 1760 he replaced the old wooden construction with the stone building still in standing and in use today. The main building was most likely designed by architect Carl Wijnblad in simplified French rococo style and had two floors, plastered façade and two wings.
Malla Silfverstolpe, 1782-1861, grew up in the castle. Her diary gives a vivid and fascinating account of life at Edsberg during this time. The Rudbecks were owners of the castle for about 200 years, upon which the county of Sollentuna assumed ownership in 1959. It has since then been used for higher musical education.
The castle has undergone extensive renovation and housed Sveriges Radios Musikskola (the music school of the Swedish National Radio). It now houses Edsbergs Musikinstitut; the independent chamber music division of the Royal College of Music, Stockholm.
A section of the castle and the garden is rented out for private and corporate events. An art gallery, Edsvik Konsthall, is located on the castle's premises.
References:The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
