Frösö church is one of Jämtland's major tourist attractions. It can be dated back to the twelfth or 12th century. The altarpiece and pulpit are both from the 18th century. The attractive and characteristic bell tower, which stands separately from the church, was built in the 18th century. A raging fire in 1898 left only the foundations remain, but all the interiors were rescued. Archaeological investigations indicate that the church was built on a pagan site of sacrifice.
The church has become known among other things, by composer Wilhelm Peterson-Berger's compositions. The magnificent view around Frösö church has also made it one of the most popular wedding churches in Sweden.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
