Uppsala Cathedral in the context of "Alsike, Sweden"

Religion in Sweden has, over the years, become increasingly diverse. Christianity was the religion of virtually all of the Swedish population from the 12th to the early 20th century, but it has rapidly declined throughout the late 20th and early 21st century.

High church Lutheranism is a movement that began in 20th-century Europe and emphasizes worship practices and doctrines that emphasize the sacraments and liturgy, along with a robust devotional life. In the more general usage of the term, it describes the general high church characteristics of Lutheranism in Nordic and Baltic countries such as Sweden, Finland, Estonia and Latvia. The mentioned countries have more markedly preserved pre-Reformation, Catholic traditions and eschewed Reformed theology. From the earliest part of its development, Lutheranism as a whole has employed elaborate liturgies and ornate sacred art. Lutheranism has viewed its faith and practice as "deeply and fundamentally catholic". It is closely related to the concept of Evangelical Catholicism, which emphasizes the catholicity of Lutheranism.

Uppsala (/ʌpˈsɑːlə/ up-SAH-lə; Swedish: [ˈɵ̂pːˌsɑːla] ; archaically spelled Upsala) is the capital of Uppsala County and the fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019.

Located 71 km (44 mi) north of the capital Stockholm, it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiastical centre of Sweden, being the seat of the Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century.

University Hall or the University Main Building (Swedish: Universitetshuset) is the main building of Uppsala University in Uppsala, Sweden. The building is situated in University Park close to Uppsala Cathedral. It was designed in Italian renaissance Beaux-Arts style by architect Herman Teodor Holmgren (1842-1914) and completed in 1887.

The building should not be confused with Carolina Rediviva, which is the Uppsala University Library building, or Gustavianum, the previous main building, which today is a museum.

Coronations of the Swedish monarchs took place in various cities during the 13th and 14th centuries, but from the middle of the 15th century onward in the cathedrals of Uppsala or Stockholm, with the exception of the coronation of Gustav IV Adolf, which took place in Norrköping in 1800. Earlier coronations were also held at Uppsala, the ecclesiastical center of Sweden. Prior to Sweden's change to a hereditary monarchy, the focus of the coronation rite was on legitimising an elected king.
