Church of St. Adalbert

The synagogue in Kielce was built from 1903 to 1909. During World War II, the Nazis completely devastated the interior of the synagogue, turning it into a prison and warehouse for stolen Jewish property, and at the end of the war, the building was burned down. Reconstruction of the building began in 1951 and was completed in 1955 in the socialist realist style. The synagogue was then turned into a provincial state archive.

Kielce Cathedral is a Baroque church built in the 18th century on a former Romanesque church dating from the 12th century. The church did not become a cathedral until 1805. The church, its chapel from 1760 and the bell tower from the middle of the 17th century have been entered in the register of real estate monuments. The cathedral also contains many movable monuments inside such as altars, chalices and monstrances.

The Church of the Holy Cross was built between 1903 and 1963. The construction of the church was interrupted many times, mainly during the two World Wars but also due to the repercussions of the world crisis that hit Poland in the 1930s. Nevertheless, the builders remained faithful to the original neo-gothic design of the church by Stanisław Szpakowski.
