This three-nave church in neo-Gothic style at the heart of the city on Freedom Square was completed in 1867.
The stylish design of the altar and the painting Christ on the Cross (Karl Gottlieb Wenig, colourful stained-glass windows) and the chandeliers, which are older than the building itself, make the church radiant. The oldest church bell with an Estonian text is also located in the church tower (1872). 
In the St. John's Church you can admire Dolores Hoffmann's ten stained-glass windows, which tell various stories from the Gospel of John. The windows of John and Luke the Evangelist are illuminated in the dark.
