The Church of the Reformation, which dates back to 1721-1733, is one of the few Calvinist churches in Latvia. The church is richly decorated with pilasters and surmounted by a small tower. After a fire, it was rebuilt in 1805 and the ground floor was converted into a warehouse. During the Soviet occupation, the building was converted into a recording studio.
The large Reformed church is the most distinctive building in Debrecen, the largest Protestant church in the country. Built between 1805 and 1824 in neoclassical style, it is located on a site where churches have been erected since the Middle Ages.

The Reichshoffen Synagogue is a former place of worship built in the middle of the 19th century. The building was built on the site of an even older synagogue for the Jewish community that had inhabited Reichshoffen since the Thirty Years' Wars. The neo-Moorish building was damaged during the Second World War and ceased to be used in 1967.
Notre-Dame de Reims Cathedral is known to have been the site of almost all the coronations of the kings of France since the 11th century. It was here that Clovis, the first king of the Franks, was baptized at the turn of the 5th and 6th centuries, an event retrospectively considered to be the foundation of the French monarchy. The current Gothic cathedral was built from the 13th to 14th centuries, on a site where cathedrals have been built since the 5th century. The building was severely damaged during the First World War, but has been rebuilt and listed as a UNESCO World Heritage Site since 1991.
Reinli Stave Church is a single nave church (long church) from the 13th century or at the beginning of the 14th century. The church was restored in 1884–1885 and 1976–1977.

The Remonstrant church from 1883 was given a completely new destination in 2006. The church and outbuildings have since been widely used for meetings, trainings, conferences, workshops, concerts and lectures.
The current site of the cathedral has been used as the seat of a bishopric since the 6th century. It is likely that it was built in place of an older sanctuary. The old building was completely replaced by a Gothic church in the 12th century. In 1490, the tower and the western facade of the Gothic church collapsed. An endless reconstruction of the western massif was undertaken, which lasted 163 years and resulted in the granite facade that we know today, which is largely in the classical style.
The cathedral of Rēzeknes was first built in 1685 as a wooden church given to the Jesuits. It was rebuilt in 1750 but burned down in 1887 during a storm. The construction of the present stone church began at the end of the 19th century and was completed in 1902. In 1995, the then Pope John Paul II granted the church the status of a cathedral.
