The wooden posts and roof were replaced from 1669 to 1675 by Andreas Klengel using Tuscan stone columns and a groin vault with stuccoed ribs.
Chancel and nave have high two-storey, four-panelled round arch windows with tracery and a rich profile.
The lavishly decorated portal at the west end dates to the period before the great fire and has an ordered ogee arch and Verstabungen.
The vault of the light, seven-bay nave, despite its Gothic arches, is characterised by stucco in the baroque style.
The stuccoed cloth hangers (Tuchgehänge), fruit cords (Fruchtschnüre) and 25 angels' heads on the balustrades of the surrounding rood screens were prepared under the direction of Italian stuccoer, Alessandro Pernasione, who had been commissioned by the senior state architect (Oberlandbaumeister), Wolf Caspar von Klengel.
The richly decorated altar is built on wooden columns and has scrollwork by Andreas Hellmert dating to 1617.
During the renovation and repainting of the nave in 1896 a stained glass window was installed by the Zittau firm of Türcke, which portrays Christ as the judge of the world.
The Late Gothic carved altar from a workshop in Freiberg was manufactured in the early 16th century and comes from the hospital church in Lengefeld that burned down in 1892.
In the centre panel Mary is depicted between Saints Peter and Paul; on the inner face is the Passion and on the outer sides the Evangelists.
