of the Lutheran Archbishop of Uppsala and the primate of the Church of Sweden. Across the street from the Gustavianum in the University Park stands the University Hall, erected in 1879–86 in Italian renaissance style. The Uppsala University Coin Cabinet is located in the university main building. Not far from the University stands the Uppsala University Library (Carolina Rediviva), the largest library in Sweden, with over 5 million volumes and some 60,000 manuscripts. The building was built in 1820–41. On a circa 35-metre high hill to the southwest of the University Library stands Uppsala Castle. Its construction was initiated in 1549 by King Gustav Vasa, founder of the Vasa royal dynasty. Today the castle holds several museums, among them the regional art museum, and is the residence of the Uppsala County Governor (landshövding). There are several botanical museums in Uppsala related to the world-famous 18th century botanist and zoologist Carl Linnaeus; the Botanic Garden next to the castle, the Linnaean Garden in the city centre, and Linnaeus Hammarby, Linnaeus' summer house in the countryside village of Danmarks Hammarby south of the city. north of Uppsala city lies Gamla Uppsala (Old Uppsala), the location of the pre-Christian settlement of Uppsala which later provided the new name for the medieval settlement further south. There are few remains, with the exception of several huge burial mounds of pre-Christian monarchs and the previous cathedral from 1164 A.D., traditionally said to be built over the old heathen temple (and recent archaeological investigations seems to support this notion). The site was a major religious centre in Scandinavia in pre-Christian times. After the old cathedral church burned down around 1240 it was only partially restored to a more modest size as it no longer was the seat of the Archbishop. The Gamla Uppsala Museum exhibits archeological finds made during excavations in Gamla Uppsala and related finds from other parts of Uppland, as well as exhibitions on the history of the site itself. Transportation Trains depart Uppsala Central Station in three directions. There are trains to the south , Arlanda, Stockholm and Linköping, to the northwest, Dalarna and Sala, and to the north Gävle, Sundsvall, Östersund and to the northern half of Sweden as well as sleeper trains to Narvik in Norway.
