Linköping

Linköping Cathedral
(http://www.linkopingsdomk...). The first church was built on this site in the 12th century, and was expanded regularly over the following centuries, culminating on the 19th-century tower. Linköping is said to have had the first Christian bishop in Sweden, in a time when Lund was Danish and Uppsala was pagan.
Linköping Castle
(http://home.swipnet.se/wi...), from the 13th century, was the bishop's residence until the Lutheran reformation in the 16th century. Now it is the residence of the sheriff landshövding for Östergötland county. The castle also houses a museum.

The City Hall (http://home.swipnet.se/wi...) stadshuset was erected as a secondary school läroverk in 1864. Above its entrance is the Latin phrase "Initium sapientie timor Domini" fear of the Lord is the beginning of all learning. This power triangle is on the crest of a minor hill from which the city's main street Storgatan slopes down to the main square Stortorget and further down to the bridge Stångebro across river Stångån. In its extension, this street was part of the old country road to Norrköping and Stockholm.

Public Buildings
Situated around the hill crest are the public library, the administrative buildings for the diocese, the bishop's residence, and a sports house gymnastikhuset (http://home.swipnet.se/win/linkoping/60aga.htm) built in 1881. The current library was built in 1998, but the collections of the old cathedral library date back to before Gutenberg. Further north are the concert hall Konsert & Kongress, the county museum Östergötlands länsmuseum next to the Raoul Wallenberg plaza, and two secondary schools Katedralskolan, Berzeliusskolan.
Gamla Linköping
Old Linköping and Valla fritidsområde. An open-air museum, west of the city centre. Beautiful buildings once situated in the centre of Linköping have been saved from demolishion and moved to this area to make it's own little town. Here you can practically enjoy life of Linköping in the 19th century. The citizens of Linköping enjoy taking part of the life and you can see people actually dressed up and working as citizens of Gamla Linköping. Also remember to buy locally produced chocolate and candy to reduced prices.
