Linköping (pronounced "Linshooping") is Sweden's fifth biggest municipality. It is in the northern part of the Götaland region and is the capital of Östergötland county. It has about 135,000 inhabitants in the municipality, including some countryside, and just under 100,000 in the city proper.
The city has the advantage of being a major city with all that it entails yet retaining the cozy quiet small town feel, largely due to the lack of tall buildings (a result of the military airfield just outside the city).
The cathedral in wintry Linköping
Linköping is the clerical and administrative centre in a rich farmland district, the province and county Östergötland.
The town was founded during the Middle Ages and is therefore one of the oldest cities in Sweden. The cathedral and the castle are two medieval buildings that are still standing.
At the "battle of Stångebro" in 1598, the city fought on the Catholic side and lost. A memorial of the battle is found just outside the city centre. The following "bloodbath of Linköping" in 1600 is remembered with a memorial at the main square.
Linköping has a university and the students are a central part of the city's life both day and night.

Saint Lars' Church in the city centre
Linköping Cathedral. 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.

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 ) built in 1881. The current library was built in 1998, but the collections of the old cathedral library date back to before Gutenberg.
