Adolf Fredriks kyrka ("The Church of Adolf Frederick") was built in 1768-1774, replacing a wooden chapel from 1674, which was dedicated to Saint Olof. René Descartes was first buried to the cemetery in 1650 (before his remains were moved to France). Inside the church is a memorial to the memory of Descartes installed by Gustav III. Other famous people buried in the church cemetery include Swedish Prime Minister Olof Palme who was assassinated only a block from the church, as well as Prime Minister Hjalmar Branting.

The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
